Why are you changing the file modes of our metadata files?

[ni-jfitzger]

Note: if you pull the latest changes, the system tests will pass.
Not really a requirement for this change, but the PR Checks would look better.

I did not explicitly touch those files, doing tox -e codegen touched those files, and I just committed.
