Use "nightly" version for all dependencies on main

[huntie]

Summary

Motivation: Reduce maintenance on the main branch of this repo.

• Remove "0.x.0-main" and "1000.0.0" placeholders for React Native package dependencies (which will not resolve without a yarn link setup). Instead, simplify by using "nightly" pointer — resolving to the latest nightly available on npm (effectively, each -main version).
• Simplify root package.json (drop version, drop npm-specific fields that are redundant for a project config).

I'm sure there is a script somewhere that updates those versions whenever a new branch cut happens, have we verified that such script keeps on working?

[huntie]

@cortinico No conceptual conflict — this is simply the starting state of these files on main, before we cut branches. Scripts will continue to parse and write new version values to each dep key 🙂

@cortinico I think that with this change, we don't have to run the script that bumps the dependency on main anymore, right @huntie?

[huntie]

@cipolleschi Yes, it should entirely delete that part of repo maintenance.

Feels good to me, let's wait for @cortinico thoughts

@cortinico I think that with this change, we don't have to run the script that bumps the dependency on main anymore, right @huntie?

When you cut the branch you want the 0.xx-stable branch to have a package.json that points to 0.xx.0 packages and not nightly packages, so that logic needs to be updated

[huntie]

@cortinico Sure, as far as I can tell:

1/ The existing scripts do this.

template/scripts/updateReactNativeVersion.js

Lines 50 to 58 in ef04031

	pkgJson = updateDependencies(pkgJson, {
	dependencies: {
	'react-native': version,
	...normalizeReactNativeDeps(pkgJson.dependencies, version),
	},
	devDependencies: {
	...normalizeReactNativeDeps(pkgJson.devDependencies, version),
	},
	});

2/ Our generated commits happen on every RC, so as far as I can see there is no process gap (recent RC0: 8c5f5e9).
