@BridgeAR are there any other semver-minor changes to assert we should look at backporting for the next 8.x?

It would probably be worth also backporting the two commits from #19650 at the same time, since they modified the assert.rejects API. The unmodified version of the API from #18023 never appeared in a release (see the note at the top of #19650 for more info).

This updates the test in `test/parallel/test-assert-async.js` to add an
assertion that the Promises used in the test end up fulfilled.
Previously, if an assertion failure occurred, the Promises would have
rejected and a warning would have been logged, but the test would still
have exit code 0.

This updates `assert.rejects()` to disallow any errors that are thrown
synchronously from the given function. Previously, throwing an error
would cause the same behavior as returning a rejected Promise.
