glossary: add <abbr> tags everywhere!

[jorgeorpinel]

Once #431 is merged,

There will be an initial glossary.js file with a set of terms we want to add <abbr> tags around in the md files so they display glossary tooltips on hover and dotted underline links to click on (for mobile).

• Implement mobile view per WIP: add glossary with some basic DVC terms #431 (review) @algomaster99

• Add missing glossary terms listed on create glossary #424.

• We have to use discretion to chose at least one occurrence of each term in all the docs to have this functionality. Note that some of these occurrences are currently linked to some other doc and would need to be unlinked (but an equivalent link should be in the glossary tooltip).
  Note that the "workspace" and "DVC project" terms are already fully applied as well as "cache directory" and "the project" (but maybe not simply "cache", so start from there).

  Per WIP: add glossary with some basic DVC terms #431 (comment) and WIP: add glossary with some basic DVC terms #431 (comment)

• There should be a section or a few sections called Basic Concepts in the user guide that is/are properly written on a user-level language explaining some missing concepts. The glossary tooltips could point to these sections among other things. An example would a DVC-file term and this link: https://dvc.org/doc/user-guide/dvc-file-format Extracted to guide: new DVC Concepts section #550

• Review the terms and their descriptions in the glossary.js file, vs. all the existing definitions in md docs, possibly making the ones in docs shorter now that we can have the glossary tooltip over those occurrences of each term.

Possibly also add functionality to the glossary engine module so all the abbr terms in each doc are displayed on the right side bar (when visible, for wider screens) beneath the edit and chat buttons.

@jorgeorpinel Let's start working on this issue now. :)

[jorgeorpinel]

Feel free to get going with fixing the mobile view and open a PR, sure! Thanks @algomaster99

[jorgeorpinel]

Any luck so far with the mobile view @algomaster99 ? I can work on the other checkboxes in this issue description but that one I feel you're the best equipped to tackle.

Of all the glossary: issues, this I think is the most important one so I'm giving it p1 label @shcheklein but please correct me if i'm wrong.

[jorgeorpinel]

@shcheklein also what do you think of the parts of the description I scratched out: "There should be a section or a few sections called Basic Concepts..." and "Possibly also add functionality to" (at the very bottom)? Please confirm we no longer need those, otherwise I'll create a separate issue for any relevant one.

[shcheklein]

@jorgeorpinel I think we still need some Basic Concepts section in the User Guide - a section per each, that explain stuff in more details than the glossary.

I agree to remove the second one for now.

Extracted "There should be a section or a few sections called Basic Concepts..." to #550.

Ping @algomaster99 still around? 😃

[algomaster99]

@jorgeorpinel I am really sorry I am not contributing these days but I have been really busy. Can you quickly update me what all do I need to do as of now? Thanks!

No worries just let us know if you're no longer available, you've already helped a lot 👍
But if you can try to address the first checkbox here, that would be great:

• Fix mobile view first, actually. Per WIP: add glossary with some basic DVC terms #431 (review)
