Unable to overwrite an existing draft release

[mitchelbaker-cisa]

I've been building a workflow to automate our project's release process. We create release branches then merge to main, so the objective was to create a draft release when a release PR is created. If new features are merged into the release branch, then this requires the existing draft release to be updated. However, after tinkering around and looking at other issues this functionality is not possible.

There's already proposed PRs with a fix along and a few issues requesting this.

PRs:

• Allow updating draft releases #245
• Fix updating draft releases #255

Issues:

• Draft release could not be overwrited #284
• The body of a release is overwritten with the content of body_path or body #362
• Unable to create/upload/publish because can't update draft #356

As noted in the README,
💡 When the release info keys (such as name, body, draft, prerelease, etc.) are not explicitly set and there is already an existing release for the tag, the release will retain its original info.

I have each of these keys so the existing release should be updated here. Another action is being used to generate the changelog but it functions as expected, if anything action-gh-release should recognize that the body has new information and update accordingly.
