Kakoune has many users who may not have an IRC bouncer set up. As a
result, they might not have the best experience using IRC.
Let's lower the barrier of entry by linking to the Matrix IRC bridge,
which has a web client with persistent chat history (though for these
bridges, users can only see history from after they joined).
Our peer projects like Neovim and Helix make heavy use of Matrix. They
use proper Matrix channels which may have more features than IRC
bridges.
The icon is fairly random, I didn't find anything resembling the
matrix logo.

Since Kakoune has moved to libera, it doesn't make sense for the pages to link to or mention freenode - I've updated them to point to and mention libera / its webchat instead.
Change the 'Documentation' links to match the URL pattern of the 'Get Started' links
(and of the 'Try Kakoune!' button in the homepage).
Also add the missing icon for the 'Get Started' link in the gallery.html page.
This commit adds a page to the navigation bar that will list
repositories on Github that have the "kakoune" topic set. The order
of the repositories is decided by Github (stars), and an attacker
could have their rogue plugin listed on the page, therefore users
are warned to use the plugins at their own risks.
