Chat link is invalid

[nospam3089]

README.md lists https://discord.gg/x2gKzst as a Chat link for this project.

After jumping through all the hoops and loops of creating an account with discord, including verifying ones email address and excelling in botanical skillz for the captcha, one is finally merely greeted with an error message reading: This invite may be expired, or you might not have permission to join.

Maybe someone please could update the invitation link to a working one?

The link should probably have also be update to zulip: https://http-rs.zulipchat.com/

Though, that's not really used either.
