strip_or_import no longer fixes types of the form "module.foo[str,str]"

Bug Report

Stubgenc's strip_or_import no longer fixes types that contain a [.

This seems to be caused by #14564

Specifically, [ is not included in the match for the regex replacement. This causes the subtype before the [ to not be replaced as it should be.

To Reproduce

Create a py extension with a function which has a return type referencing a class in the local module with [ in the type.

Expected Behavior

The fully-qualified module should be excluded.

class KeysView[str]:
    ...

class MyMap:
    def keys(self) -> KeysView[str]: ...

Actual Behavior

The fully-qualified name is left behind and not replaced.

class KeysView[str]:
    ...

class MyMap:
    def keys(self) -> full.module.name.KeysView[str]: ...

Localiza la implementación de strip_or_import de stubgenc e inspecciona el reemplazo mediante regex que gestiona los nombres cualificados. Reproduce el problema con un tipo de retorno como KeysView[str]; se considera completado cuando el prefijo del módulo local se elimina del subtipo y se conserva el tipo entre corchetes.
