Next steps: how to set up weather api example

[canadaduane]

The intro experience is great, all the way up to setting up the weather API. Here is my experience:

1. vim ~/.dune-prelude shows an empty file, and trying to write to it, vim says "Can't open file for writing".
2. I switched to a graphical editor (Zed, in my case) to edit .dune-prelude and/or .dune-secrets since I couldn't figure out how to edit these files starting from dunesh
3. I tried set-weather-api-key "0123abc" in .dune-secrets but it didn't work
4. I tried adding WEATHER_API_KEY=0123abc to .dune-secrets but it shows an error
5. I tried adding my city as the second arg, set-weather-api-key "0123abc" "Sandy, US" but I don't see the weather
6. My city, "Sandy, US" has 3 variants, how do I specify My "Sandy, US" (Utah)?

Thanks!
