Remove param from SCIM types

[t2y]

According to https://datatracker.ietf.org/doc/html/rfc7643#section-10.2.1, there is no param in the type definition.

 type
    The entity type, which is either "schemas" or "api".

Oh, I didn't notice that statement. It indicates that param might be added in the future. However, I couldn't find a real URN example including urn:ietf:params:scim:param when I tried to write a test code to parse it.

Either one of these is incorrect, I guess. Should we call for a report to the SCIM WG?

  Namespaces with type "api" (e.g., "urn:ietf:params:scim:api") and
  "param" (e.g., "urn:ietf:params:scim:param") are reserved for
  IETF-approved SCIM specifications.

Of course, you can reject this PR until the specification is clarified.

I guess that would be the best thing to do.

No need to. We can keep it open till more clear info emerges!
