Schema linting errors when using this package

[damienpontifex]

I'm shifting over to use federation and directives with this package, but now getting linting errors (from Apollo Studio) within our pipeline. I believe they shouldn't exist and hence the issue here

I've bumped HotChocolate libraries from 13.5.0 to 13.6.1 and using 1.2.1 of this apollo package.

The schema file is generated by running rover subgraph introspect "http://localhost:5000/graphql" > "my-schema.graphql"

And then we do rover subgraph check <graph-ref>@<variant> --name my-service --schema my-schema.graphql

Is this an issue in the schema rover is introspecting/generating? Or something about this package addition (reason I ask this as it wasn't failing prior when just utilising HotChocolate 13.5)?
