Some proposed updates

[brody2consult]

• alphabetical devDependencies in package.json
• drop support for non-functional test scripts (and remove from the Tasks list)
• drop support for non-functional eject-web task (this commit closes the issue that I raised in eject-web failure #16)
• add functional yarn start-expo script (and mark existing start-native script as "not supported")
• Expo 28 update (note that I had trouble with newer versions of Expo, as explained by expo update #14 (comment))
• ignore .*.swp (maybe this should be left to the user's global git config?)
• require logo image in the beginning of src/App.js (a little cleaner, maybe a little more efficient)
• Remove StatusBar usage not needed (this was causing an issue with using react-primitives)

I would be happy to raise some or all of these updates in separate PRs if needed.

I will likely continue with a fresh new template from expo init, raising this PR for the benefit of existing users.
