This gem will be moved out of the standard library in Ruby 3.5.0.
While the website can still build fine with Ruby 3.4.x, this won't
be the case anymore with the latest Ruby version once 3.5.0 releases.
Ruby 3.4 removed several standard library packages, so they have
to be installed as gems instead.
This also updates Jekyll to use a version that's supported in Ruby 3.4.
The minimum required Ruby version is now 3.2.
This PR replaces the current CMS website with a static version of it built using Jekyll.
- Everything should be working 1 to 1 with the same permalinks except for the `/news` page (not articles) which was renamed as `/blog` (old links will redirect to new ones).
- The showcase entries on the home page now redirect to their showcase page in our site so that the user can choose which store front or page to visit next.
- I also changed the first link from the nav bar to go to the showcase page since the features one is still pretty outdated.
