• Add 144 Jekyll Plugins under the category 'Jekyll Plugins'.

This looked like a fun and easy task to pick up, but a query of RubyGems showed there were over 2,000 gems that matched jekyll. I filtered for ones with more than 8,000 downloads, and updated after 2022, which gave me 788.

Before I go through and copy all those over, do y'all still want this issue from 2020? Would this be mergeable if I finished it? Do you have any advice or guidance to build this list more efficiently or gems you might not want included?

Before submitting your pull request:

• If you're referencing a gem by its GitHub repository (e.g. rails/rails), please verify
  that it is not packaged as a Ruby gem. (If it is packaged as a gem, please reference it
  by its gem name instead, e.g. rails.)
• Make sure the CI build passes, we validate your proposed changes in the test suite :)
