Twitter: hook up the bot to tweet out a message calling for help when `beginner-friendly` issue is created

Only when created or also updated?

Can discuss what the message should be here.

BTW if we do this we need to make sure we have a good template or set of steps for people to follow

No files, tests, or entry points are named. First resolve whether tweets are sent on creation, updates, or both, and agree on the message and the template or steps linked for contributors. Then locate the bot's GitHub issue event handling and Twitter integration, and define completion as the agreed behavior working for a beginner-friendly issue.
