Allow commit to be done via github bot

[tielur]

Would it be possible to allow a setting to make the commit to the deploy branch be the github bot?

Specifically here:
https://github.com/helaili/jekyll-action/blob/master/entrypoint.sh#L183-L184

I'd like to ideally set GITHUB_ACTOR to github-actions[bot]

There's a few other actions I've seen do this:
pypa/pipenv#4328
pypa/pipenv#4329

My main reasoning for wanting this is so that my github commit history doesn't get flooded by action commits

I'm more then happy to open a PR if this is something that makes sense

Yes, that would be really awesome and from my point of view a great addition to this action. +1 for this feature!

Another action where this is implemented: https://github.com/peaceiris/actions-gh-pages#%EF%B8%8F-set-git-username-and-email

+1 for this feature request. Hope it will be implemented!

I have a fork that I made that I've been testing and it works well. I'll work on cleaning it up and open a PR soon
