Fix MR draft RegEx

See merge request gitlab-org/gitlab!72454

Remove "Note" wording from Note alert

See merge request gitlab-org/gitlab!72432

but the .replace doesn't replace anything.

Style updates to Protected Environments page

See merge request gitlab-org/gitlab!72407

This fixes a RegEx that checks whether an MR is a draft in the MR
edit/create page. The RegEx was recently changed in a way that prevents
it from detecting the current MR state and breaks the toggle draft
status feature.
