docs: add plugin comparison table

[iProdigy]

~~I put n/a for cells that are dependent on another cell being true that was not; could change this to :x: if desired~~

[pajlada]

I think just :x: instead of n/a is fine

For some things where dink has a checkmark, it's not necessarily just "click enable & it works", it would be interesting to have links to documentation as part of the :heavy_check_mark: . not necessary as part of this PR

~~Should we abbreviate the column names?~~
