Slack notifier for release candidates?

[cary-ilm]

@jmertic , I'm trying to automate as many of the release steps as possible. When I tag a release candidate, i.e. push a tag of the form v3.3.1-rc or v3.3.1-rc2, I post a message:

OpenEXR v3.3.1 is staged for release at tag v3.3.1-rc and is available for testing.

Could this action be extended to support that feature? Triggered on pushing a tag, with a configurable subject/first line?

Thanks!

Let me look more into this. I think we can likely find a way to handle this.
