[PatchBodyParametersSchema] Property type in common-types ManagedServiceIdentity is required

[mikeharder]

Rule PatchBodyParametersSchema generates an error if a spec uses ManagedServiceIdentity in a PATCH request:

PatchBodyParametersSchema
Properties of a PATCH request body must not be required, property:type.
RPC-Patch-V1-10

The spec author believes their spec is correct, and suppressed the error.

Is this the correct resolution? If so, should either the rule or ManagedServiceIdentity be modified to avoid this error going forward? I think all types under common-types should pass all LintDiff rules, for all intended usages by spec authors.
