openmeteo: use 'current' instead of 'current_weather'

The 'current_weather=1' parameter no longer appears in Open-Meteo
documentation, and is likely deprecated.

Handling that response format also presented us with intermittent bugs,
especially around fetching humidity data from an hourly series based on
timestamp data that wasn't necessarily aligned with that series.

Using the 'current' parameter, we can directly request exactly the
weather properties we need, and nothing else.
