docs: remove references to Expo Go since no longer an option

[frankcalise]

Please verify the following:

• [ ] yarn test jest tests pass with new tests, if relevant
• [ ] yarn lint eslint checks pass with new code, if relevant
• [ ] yarn format:check prettier checks pass with new code, if relevant
• [ ] README.md (or relevant documentation) has been updated with your changes
• [ ] If this affects functionality there aren't tests for, I manually tested it, including by generating a new app locally if needed (see docs).

Describe your PR

In v10, Expo Go is no longer an option when creating a new project. This PR removes a bunch of those references and adds clarity to why it was an option to remove it based on Expo's recommendation.

It also clears up some text around using vanilla cli vs expo cli etc, which was more of a v8, Maverick thing and no longer applies
