Create new github-bot personal token for nodejs/tweet automation

This week, @joesepi and I spent some time on automating the nodejs/tweet repo so we can consistently and easily get out any tweets that should be going out regularly. We started with two, and in the process came across a tiny hitch: for one action to trigger another, we need to use a PAT instead of the Actions-provided token since one action can't trigger off of another if there's a GitHub provided token being used in the other.

Per @gr2m's advice (he is the maintainer of both Actions we're consuming), we need a PAT from the bot with the following permission:

• repo_public
