[core] configure cspell to check default modules only and fix typos (#3955)

When I saw PR #3951, I wondered why `cspell` didn't catch these typos
before. Unfortunately, the default modules were excluded from the check.
I have corrected this with these changes.

This even revealed a code error in
`modules/default/weather/providers/overrideWrapper.js`:

- before: `fetchEatherHourly`
- after: `fetchWeatherHourly`

modules/default/weather/providers/openmeteo.js
