What happened?

Description

My staging server is set to automatically deploy (via Ploi) when I push a commit. It works great, but lately we've been running into this issue.

Something on the staging site is making changes to the Project Config YAML files. I'm certain this environment is properly configured, with the allowAdminChanges setting disabled. In theory, nothing in this environment should be able to make project config changes.

Since something is making PC changes, it prevents my automatic deployments from working properly. Ploi is using a basic git pull on the staging site, but it's unable to pull because there are "uncommitted changes". If you SSH into the server and just discard those changes, the automatic deployment begins working again.

Unfortunately, I encountered this last week when I was in a hurry, so while I repeatedly discarded changes in the PC files, I never took a moment to deeply investigate those changes. So I don't recall exactly what they were, other than that they "weren't important". I believe it may have simply been comments added to the YAML files.

Fortunately (I guess), a few other people have recently mentioned this exact same issue on Discord. So perhaps between the group of us, we can track down whatever you need to fix the issue.

Thanks for looking into it!

Steps to reproduce

Expected behavior

If allowAdminChanges is disabled, nothing should ever be written to the Project Config YAML files.
