Use ResponseParameters direclty in model dump

[NaqGuug]

Pass the new ResponseParameters to model dump instead of explicitly setting attributes and excluded_attributes.

So this (req is an instance of ResponseParameters)

user.model_dump(
    scim_ctx=Context.RESOURCE_QUERY_RESPONSE,
    attributes=req.attributes,
    excluded_attributes=req.excluded_attributes,
)

becomes this

user.model_dump(
    scim_ctx=Context.RESOURCE_QUERY_RESPONSE,
    response_parameters=req,
)
