GitHub deprecation notice?

I have Dreamweaver tied to a GitHub repository for a wordpress theme, and use WP Pusher on a UAT site set to update on push and again on a PROD site set to update on manual request.

I receive semi-regular deprecation notices from GitHub when making updates:

You recently used a password to access the repository at account/repository with git using git/2.29.2.windows.2

These notices have some sort of "don't send too often" on GitHub's end, so it's not 1:1 with any of these 3 actions (interact with dreamweaver, UAT updates, PROD updates). WP Pusher confirmed that they updated their methods over a year ago. We do have a slightly wonky PROD environment so I am slightly suspicious that there may somehow be plugin files only claiming to be updated.

But, I have no idea how any of this ACTUALLY works. I understand Dreamweaver points to a git install and doesn't actually contain it? I got it working and stopped touching it. So maybe there's something about how I have git set up on my end that isn't right?

Search results are giving me documentation that is likely unrelated and also way more technical than I'm down for. Is there anything I can do to investigate this on the Dreamweaver side?
