API endpoint to edit a release in the Release Management add-on

Description of the feature request

We would like to be able to edit a release in the Release Management add-on through the Bitrise API.

We noticed that the API already support creating releases, but the documentation doesn’t include an endpoint for editing it.

Use case / for what or how I would use it

We are changing the release branch of the release in the add-on from our main branch to a release branch we create to lock the release changes.

We would like to automate this step by making an API call from one of our workflows.

Thanks @nicolas.iensen for the detailed feature request.
