Consider using NON_INTERACTIVE_SHELL from context to detect even as coming from CI

[Martinsos]

In wasp-lang/wasp#1586 we added new "NON_INTERACTIVE_SHELL" value to our telemetry. We think it should directly correspond with if Wasp is running in CI or not, but we are not yet 100% sure, so we want to first see how it behaves in wild.

We should look at which events in PostHog have this value, and if it indeed corresponds to what I wrote above. If that behaves as it should, then we should start using it in our analytics here in wasp-bot to categorize all events that have this value in their context to be recognized as CI events!
