When using allowUpdates, the date in the release is not updated:

From this discussion.

Describe the solution you'd like

I understand that github does not update the date if you change the assets. This is understandable. However, it would be great if there was an additional option: deleteExistingRelease that allows this action to delete an existing release if one exists, before making the an updated version of the release. This would really improve this action in cases where people have nightly builds and wouldn't change any existing behavior.

Describe alternatives you've considered

The only alternative is to use a different action, which is not ideal since I believe this functionality fits well within the scope of this action given that the allowUpdates function is present.
