@module-federation/nextjs-mf version 8.4.0 breaks API routes

[rdenman]

Describe the bug

After upgrading to version 8.4.0 of @module-federation/nextjs-mf, API routes (defined in pages/api/xxxx) break with the following error:

Federation Runtime Module not found. In the current runtime

Downgrading to version 8.3.X resolves this.
