The current version of blueprint-compiler used to compile is different from
the version used to run the format check. This means that running the formatter
locally does not get the format check passing.
This commit changes the format check from getting the blueprint-compiler from
the latest Fedora image to getting it from the GNOME OS OCI nightly image,
ensuring that it is always up-to-date.
