Use Set.symmetricDifference() in sonarqube-mapper once TypeScript is updated

[mikeBoterf]

In PR #7791, the set equality check in discoverIssueStatuses() uses a manual comparison:

const sameAsDefault = defaultSet.size === denySet.size &&
  [...defaultSet].every((s) => denySet.has(s));

Once the TypeScript version is updated to support Set.symmetricDifference() (MDN docs), this can be simplified to:

const sameAsDefault = defaultSet.symmetricDifference(denySet).size === 0;

Node.js 22+ already supports this at runtime — it is only the TypeScript type definitions that are missing.
