Maybe we should improve recovery here? (Not in this PR)

This is because of the is_non_raw_ident_where?

No, because default is an identifier.
It's more important for async which performs an edition check on the span, but I used normalization for all enum Foo { Yes(Span), No } keywords for consistency.

And this is also because of eat_keyword dealing with identifiers? Although check_keyword doesn't seem to be using normalized_token... but normalization does happens automatically in bump_with.

Same answer as in #69579 (comment), const is an identifier.
eat_keyword works correctly because it uses token.ident() internally which uses normalization.
