ci: fix ReactNativeDependencies resolution and improve job names

Map ReactNativeDependencies version to upstream RN using the same
peerDependencies pattern as Hermes. For the main branch (1000.0.0),
fall back to the latest stable RN release from NPM.

Also improve Build SPM job names for readability in the GitHub UI.
