How to update diag_table in ufs-weather-model repository

[mdtoyNOAA]

I am preparing a PR that adds new optional diagnostic outputs for the unified_ugwp drag suite in the CCPP repo. These will be activated by new entries in the diag_table file. In my ccpp-physics branch, where should I put these lines? Is there a "master" version of the diag_table file where I should place them? Thank you.
