Add label support

[mdpete4]

This PR will add support to specify a list of labels you would like to add to the created issue.
This is EXTREMELY valuable in slack integration as I can filter the notifications sent to individual channels based on the issue label.

To test, I created a release of this action from my fork and utilized it in my workflows. I will be using my fork version until this PR is merged.

Apologies, I missed that the other PR is out of date - will re-open and wait to see if they address our requests. If they are addressed, I will re-close this PR. Thank you for your contribution :)
