Infrastructure and community related

These tasks are for the great Biome community and infrastrcture.

• Create a chat.biomejs.dev sub-domain, create a redirect to the discord invite link, and change all the occurrences to use chat.biomejs.dev

Developments

• For anyone who has the right to modify the issue, please add additional tasks to the list.
• We plan to merge changes to the next branch, and regularly rebase main into next until we reach a point where we can merge next into main.
• We will regularly rebase main into next. Please DOT NOT USE git merge. Please use git rebase
• For anyone involved in the developments, please enable git rerere for your sanity. This feature will cache all the conflict resolutions on your local machine, so next time you happen to have the same resolution, git will apply it automatically. Very useful when rebasing the same branch.
• Create an issue every time you start working on something, so GitHub will automatically automate the workflow (it will tick the checkbox once the issue is closed).
