jetbrains extension not builtin

[gregzuro]

The jetbrains extension doesn't seem to be 'builtin' any more ( #2589 ).

All the docs (and the CLI menus and presumably the desktop app menus) are wrong.

Version: 1.2.0

@dianed-square : I see this in a closed PR:

TODO future task: Update jetbrains server info and tutorial as needed per #2589

Thanks for the ping, @gregzuro ! I'll get started on the doc update
