[spec] potential typo in section 3.3.11 of wasm-3.0 spec

[4y8]

In the section 3.3.11 (Defined Types) of wasm-3.0's spec the following sentence appears:

Note that there is no explicit definition of type _equivalence_

(with the underscores).
It might a typo as I couldn't find this kind of formatting anywhere else in the spec. Looking at the context and the fact that underscores mean italic in markdown, what was originally meant could be equivalence.

If it is a typo, it would be fixed by #1928.
