Correct role levels required for Release CRUD

Current permission docs are incorrect when it comes to deleting a
Release object in a project.

When originally added, the permission was only given to maintainers or
higher to be able to delete a Release:
Commit 8f1e96c8
from ~2018

This change corrects the permissions table and updates the API
documentation to mention the roles required when creating,
editing/updating, or deleting a Release.
