fix: only show visible environments for that project in actions (#6318)

https://linear.app/unleash/issue/2-1969/actions-form-only-show-environments-scoped-to-the-current-project

Filters the environment options in actions to only show environments
that are currently visible for that project, safeguarding users from
configuring actions for invalid environments.
