spec: every type has a method set (minor clarification)

The spec states that a type "may" have a method set associated with it.
Yet every type has a method set, which may be empty. This is clarified
later in the same paragraph. Be clear in the first sentence as well.

Per the suggestion from https://github.com/DQNEO.

Fixes #44318.
