Is this in a plain environment (i.e., not using PackageCompiler or sysimages or anything)?

From the Base.pkgversion docs:

Return the version of the package that imported module m, or nothing if m was not imported from a package.

That covers the PackageCompiler/sysimg case.

Should be this, was just normal CI

For the record, I also ran into this issue in Julia v1.11 with a plain environment, not PackageCompiler/sysimg.
