Subject: [PATCH] Update pvsite_forecast.py

This PR updates all occurrences of "T" in pvsite_forecast.py so that:

Sidebar resample options are now ["15min", "30min"] instead of ["15T", "30T"].

User caption prompts the user to resample to "15min" instead of "15T".

All calls to .resample(resample) and any literal frequency strings use "min" rather than the deprecated "T".
