add PAT to clang format

[k-doering-NOAA]

What is the feature?

Pass in a Personal access token to clang format.

To use this, we will need an FIMS owner to generate a Personal access token and add it to the FIMS repo as a secret named PAT (if we don't like this name, we can change it!)

How have you implemented the solution?
