Add "Edit Release" page
What does this MR do?
Adds a new page - Edit Release - that allows releases to be edited through the UI as described in #26016 (closed).
Previously, releases could only be updates through the Release API. Release notes could also be edited through the Tags page (this MR doesn't change this feature).
Note that this MR does not add the "Edit" button to the release blocks to allow users to navigate to this new page. This piece is implement in !18411 (merged).
