Make it possible to create a Release through the UI
Problem to solve
It is only possible to create a Release using the Releases API.
Proposal
In #26016 (closed), we added the ability to edit a release using the UI. We should reuse this UI to create a new Release.
Further details
Creating a Release was included in the original scope of #26016 (closed), but this feature was trimmed in an effort to deliver value incrementally.
Creating a Release is slightly more complicated than editing a Release, because we will need the ability to select a Git tag. The current "Edit Release" page does not allow the tag to be changed, so it doesn't already have a tag selector built-in.
Documentation
This page will need to be updated with instructions on using the UI to create a Release.
