Community Update: Matrix Migration & LeilFS Rebrand

[rolysr]

We are moving our community discussions from Slack to Matrix. You can join the new space here:
https://matrix.to/#/#leil:matrix.org

We encourage everyone to join and start using Matrix, as activity will gradually transition there.

We also announce that SaunaFS has been rebranded to LeilFS. While some follow-up steps are still in progress, the project will be referred to as LeilFS going forward.

Thank you for being part of the community!
