fix: use glob patterns in package.json files array for yarn pack

npm pack treats directory entries in "files" as recursive globs, but
yarn pack does not. Use explicit glob patterns (e.g. "scripts/cocoapods/**"
instead of "scripts/cocoapods") so both tools include the full directory
contents.

This is the same fix as facebook#56407.
