Issue with Route Grouping

[raphaelobene]

This doesn't exclude the route grouping folder(s) in Nextjs.
ex. Folder structure (users), (marketing), (auth), etc.

This adds the route grouping folder/route to the route
ex. /(auth)/login, /(patientFacing)/appointments/[appointmentId], /(user)/settings
instead of /login, /appointments/[appointmentId], /settings.

The code is there to handle route groups. Please provide a repro case.
