🍒weather/noaa: Fix the URL for retreving the station list

It seems the noaa outages on the legacy API continue, and the previous URL that provided the list of weather stations is no longer working (it errors out as a 404).

There is however a probable alias/mirror that still works (w1.weather.gov).

Instead of a pure replacement, add a small fallback mechanism to also check the older URL in case it changes again in the future. At some point we might be even want to cache it in a local file.
