Topic publish has invalid return signature

[CrispyBacon1999]

The return signature for topic.publish() implies that it will always return a promise, but this line allows it to return undefined. Might be worth replacing it with return Promise.resolve() instead?

Promise<void> is returned if you have something like

async myFunc() {
  return;
}

Hmm, that's not what I experienced when running tests that use that code... https://github.com/CrispyBacon1999/ntcore-react/actions/runs/8146634551/job/22265567902
