Summary

Our builds generate files with a .mjs file extension. These are currently filtered out by ReactFlightWebpackPlugin so I am updating it to support this file extension.

This fixes #33155

How did you test this change?

I built the plugin with this change and used yalc to test it in my project. I confirmed the expected files now show up in react-client-manifest.json
