Update the project page description [#3625834]

The project page lists features and compatible modules that no longer hold on Drupal 10+. I went through each one:

Node.js integration (realtime comments): the ajax_comments_nodejs submodule is 7.x-1.x only. It did not come across in the Drupal 8 rewrite, and there is no separate project providing it. Node.js integration itself is 2.0.0-alpha2 for ^8 || ^9, so it cannot be installed on Drupal 10 either way.
Comment Goodness: newest release 7.x-1.4
Comment sort by created: newest release 7.x-1.0-beta1
Advanced Forum: marked unsupported, with only an 8.x dev snapshot.
Fivestar: 8.x-1.0-alpha5 covers ^9.2 || ^10, and 3.0.x-dev covers ^10.3 || ^11. Alive, but there is nothing in this module that integrates with it.
Display Suite: alive and current. Taking over how the comment field renders can stop ajax comments working though, see #45 in #3113225: Don't rebuild the entire comment field/thread when posting a comment.
CAPTCHA: CAPTCHA is alive, but there is no CAPTCHA specific code here, so I cannot say whether this still holds. Also, there are a ton of different CAPTCHA modules out there for Drupal.

The page also has no mention of 2.0.x, and the difference between the branches.

Drop the compatibility list on the homepage, most of the modules on it are either dead or have a known conflict with Drupal 10.
If the page says we work with a module, there should be a test that proves it.
Add a section that explains the differences between 1.x and 2.x and explains the upgrade path.
