Disallow editing environment name

See merge request gitlab-org/gitlab!68550

And we actually can't update slug as it's used by deployment
jobs(e.g. AutoDevOps) and should stay the same for the environment.

`app/views/groups/settings/_permissions.html.haml` even though it is a
EE feature. To avoid CE failures, move this feature flag into the CE
directory.
