chore(utils): resolve node builtins lint suppressions in hashing tests

[cryptodev-2s]

Explanation

Clears the 9 n/no-unsupported-features/node-builtins suppressions the @metamask/utils migration left in eslint-suppressions.json.

All 9 are globalThis.crypto in hashing.test.ts. Test files extend the nodejs ESLint config and pin settings.node.version to ^22, where the rule treats globalThis.crypto as experimental. hashing.ts is not flagged because non test sources do not extend that config.

The tests stub the exact global that hashing.ts reads, so there is nothing to rewrite. Replaced the bulk suppression with one file level disable that says why.

Test only, so no changelog entry.
