Summary

Typing !fedigrow@lemm.ee gives the autocomplete for !fedigrow[!fedigrow@lemm.ee](https://lemm.ee/c/fedigrow), which is unnecessary since all frontends correctly handle the plain !fedigrow@lemm.ee (I think even Mbin handles this correctly)

And the autocomplete incorrectly takes you to a remote instance. Also the autocomplete incorrectly shows the community name twice

shows the community name twice.

Steps to Reproduce

1. Type !fedigrow@lemm.ee
2. Click autocomplete
3. See incorrect markdown
4. Click Preview and see incorrect result

We really just need to stop having it autocorrect to a URL embed via []() and allow people to just type !community@instance.tld and autocorrect to the community without embedding the link as a link format. Especially since the backend already handles annotating the community links already without needing to do that and makes them functional on any instance, but directly linking hardcodes them to that instance which is a poor choice for remote users who will just get redirected there instead of the community on their own instance.
