Git integration for file deletion in plugin

[monpie3]

Currently, there is no way to delete documents through the plugin.
This feature would greatly improve document management and help prevent support issues such as tickets Unable to publish new document · Issue #570 · mieweb/wikiGDrive or
Issue Publishing New Document- Git error · Issue #571 · mieweb/wikiGDrive

Describe the solution you'd like
Adding a button in the plugin that executes git rm on the selected file(s), including any images or charts attached to the document.

Current flow
Delete the file from Google Drive, then go to WikiGDrive and commit the change with the deleted file.

If you delete the document from the drive it should be automatically deleted from wikigdrive upon next full sync.

I tried to remove Exam Editor and Encounter Types this way (mieweb/docs#92)
Using the plugin (opened in a different file than the one that was deleted), you can only perform a single sync, and unfortunately, this does not remove the deleted files → mieweb/docs@ac76f85.
After doing a full sync from Wikigdrive, the file still wasn't removed either → mieweb/docs@36f1099#diff-5b84e3e757f12200dc53072ce44e4b8f7fb6887a861c8e2a90a4e964ab095ab0
