Upgrade node version to 24

Change node 16 to node 20 fixes #394

Full Changelog: v2.4.0...v3.0.0

Bump version of @core/actions to get rid of the warning for set-output

From #356 update to version 16 of node and set BRANCH_CREATED environment variable instead of set-output

I've left set output there so others can update their action but added a warning not to use the output any longer.

Create from a specific sha

Included ability to create from sha

Defensive code added to remove refs/heads if the github event adds it. Thanks @aka-tpayne
