remove i2c_button

[FoamyGuy]

This repo has been deleted.

I believe this is the root cause of the update_bundles action failing here: https://github.com/adafruit/circuitpython/actions/runs/24328003133/job/71027320835

I was able to add some additional logging to the adabot CLI tool and run it locally to capture more of the outout than actions does and found this:
