gh-94512: Fix forced arg format in AC-processed resource

[arhadthedev]

Please note that this commit also removes an old way to express optional parameters (it prevented the new style generation):

 /*[clinic input] resource.prlimit pid: pid_t resource: int - [- limits: object- ]+ limits: object = None / [clinic start generated code]*/

I hope it breaks nothing.

• Issue: Fix forced arg format in AC-processed modules with custom converters #94512

I have no idea why resource module doesn't build on Ubuntu (a CI log contains neither compiler error nor any mention of the module name).

The failure manifests itself as a later inability to load a non-existent module in python -m unittest -v test.test_resource.ResourceTest.test_prlimit.

The bug is fixed.
