Feature request: allow draw-zmk workflow accept auth tokens

[ryan-ph]

I would like to use the draw-zmk workflow to automatically commit to main, bypassing any rulesets, whenever my keymaps are updated. Currently, this isn't possible because the commits are made using the Github Actions app, which can't be added as a user with bypass permissions.

Is it possible to update the workflow to accept an optional auth token so that commits can be made by a user / app with bypass permissions?

Sure, I haven't worked with an explicit auth token workflow before so if you can propose a PR that would make things move faster.
