tools: remove faulty early termination logic from update-timezone.mjs

We do not build Node.js in the workflow so
https://github.com/nodejs/node/blob/f4815fcd7691364d8139b44c1295dbc46f6ee4a8/tools/update-timezone.mjs#L18
is actually the version of `tzdata` in the Node.js in the runner instead
of what's in `main`.

The script is pretty fast even when the versions differ and there is an
update, so this optimization doesn't seem to be worth having given the
problem.
