If its a commit message then not really you are rather limited on what you can put.

If it were a pr then as long as it makes sense to the maintainers, who cares?

I believe this is an automated TestFlight push. Meaning there’s no direct user involvement, and it’s simply pulling commit messages.

I’ve always treated the voyager TestFlight as a nightly build. Use the app as per normal, report any issues you find. You re not explicitly being asked to test something in particular (despite what the TestFlight prompts suggest.)

Yes, the what to test file is release notes, they just are not populating them and are likely falling back to another string (the commit message)
