Feature: Add a "Search Authors in GoogleScholar" feature

[Christina0114]

I add a "Search Authors in GoogleScholar" in "RightClickMenu".

If user clicks a author's name, it will pop up a GoogleScholar Page:

I add “LookArthurMenu” in RightClickMenu class and also a LookupAuthorAction class. Besides, I add another CustomizedAction class to dynamically create new actions while the original StandardActions is an enum that can’t be added/ changed dynamically.

• Change in CHANGELOG.md described in a way that is understandable for the average user (if applicable)
• Tests created for changes (if applicable)
• Manually tested changed features in running JabRef (always required)
• Screenshots added in PR description (for UI changes)
• Checked developer's documentation: Is the information available and up to date? If not, I outlined it in this pull request.
• Checked documentation: Is the information available and up to date? If not, I created an issue at https://github.com/JabRef/user-documentation/issues or, even better, I submitted a pull request to the documentation repository.

Interesting Idea. Since there was no discussion and you have not tried to fix an existing issue, the discussion will have to be in this pull-request I guess. Hence, here my feedback about your UI design choice:

I am not sure if this option is important enough to show in the right-click menu. It is very specific to Google. What if we wanted to add a similar feature that links to other portals and search engines? - search shortscience actually falls into this category as well. One could also think about searching for other metadata, not just author. E.g. Opening the journal-page comes to mind. The right-click menu would become longer and longer.

1. Option: Integrate this into the entry editor next to the author field. See here:
   
   - a little hidden
   + does not take space from right-click menu
   + close to author field
   - what about other fields like e.g. editor?
   - is this really about "editing" an entry? Is entry-editor the right choice?

2. Option: Allow to left-click on certain columns in the maintable. See here:
   
   + Easy, fast access for user
   - Selecting a specific entry in the maintable becomes more difficult, because it might trigger the search for author instead of selecting the entry.
   - More difficult to implement, because has to be implement for multiple fields. Which fields exactly? Only author?
   + Something similar has been implemented for e.g. linked files. They allow users to choose a specific file from the maintable. See Fix single identifier cannot be opened on click #8838 and Allows to open identifiers from a popup in the maintable (e.g. URL, DOI, ...). Fixes issues #8758 and #8802 #8817

3. Option: Move Search Authors in GoogleScholar and Search Shortscience to Lookup
   
   + resonates with the idea of "lookup"
   - the other items in Lookup are of general nature and at the very core of entry metadata. Search Authors in GoogleScholar and Search Shortscience might not necessarily need such a prominent place in the UI.

4. Option:

   • 4A: Implement it like you did here in your pull-request.
   • 4B: Implement it like you did here in your pull-request, but go beyond that: Consolidate search authors in GoogleScholar and search Shortscience into a single search... (or something similar).

   For both:
   + you already did some work, so it does not go to waste
   + easy, fast and intuitive access to author search.
   - See critique from above.

   Currently I personally favour Option 4B, but I hope I have shown that there are multiple possibilities for implementation.

I really like the prominent button, since it helps in the "browsing" mode of JaRef.

Decision

• Create sub menu "Search..." and put "Search Google Scholar" and "Search Short Science" into it.
• "Search Google Scholar" implements following functionality: Google Scholar is searched for the title (simlar to ShortScience). This fixes Offer search in Google Scholar jabref-koppor#554.
• Put the current implemented functionality to the sub menu "Search..." (keeping the label)
• If possible, Additionally implement option 1 of Feature: Add a "Search Authors in GoogleScholar" feature #8886 (comment)
• If possible, add a similar button to "Title". The button then opens a menu with two options: "Search Short Science" and "Search Google Scholar"
• If possible, put Thilo's text + grahpics into an ADR markdown file.
