Release error caused by softprops/action-gh-release

[zonia3000]

The action softprops/action-gh-release@v2 caused the following error:

⚠️ Unexpected error fetching GitHub release for tag refs/tags/v0.3.2: HttpError: Validation Failed: {"resource":"Release","code":"already_exists","field":"tag_name"} - https://docs.github.com/rest/releases/releases#update-a-release
[error]Validation Failed: {"resource":"Release","code":"already_exists","field":"tag_name"} - https://docs.github.com/rest/releases/releases#update-a-release

I noticed a recent issue regarding something that isn't working, although it's not clear exactly what it is, so I tried to pin the action version to 2.2.1 (d412936) and the error disappeared.

I'm not 100% sure that the issue was solved by my change, since there is an older open issue about the same error, so maybe it could be something happening sporadically. We should keep an eye on this in the upcoming releases, considering that we also use them in fractal-web.
