Enhance UX on Environment Form with Loading Icon

See merge request gitlab-org/gitlab!66750

The loading icon adds nice feedback to the user that _something_ is
happening, but we only unset it in the error case as the good case (in
both editing and creating) navigate us to a new page anyway.

We also add some clientside validations following the pajamas guideline.

Finally, delete the HAML form. We don't need it anymore.

Exempt public/internal projects from job token scope

See merge request gitlab-org/gitlab!66551

We mention confidentiality (for epics, merge requests, and issues)
in various places in our docset, but we rarely linked to the pages
with the actual information. This MR adds in quite a few crosslinks
to ease the friction of finding needed info.
