feat: prefix or suffix to commit message

[nirgn975]

Problem:
When I use this action, a new commit is added to the main branch, which is trigger another workflow. The action doesn't release a new branch because it's just a chore commit. But I interested in preventing the trigger of the workflow all toghter.

Suggestion:
As of February 8, 2021 GitHub Actions supports skipping push and pull_request workflows by looking for some common keywords in the commit message.
So if you'll have the option to suffix the keyword GitHub uses to skip the workflow (like [skip ci]) it'll not run the workflow for the chore commit.
