feat(yarn-sdks): Add hook to generate Yarn SDKs

Ensure Yarn SDKs remain up-to-date. Run Prettier on VSCode settings
within the same hook to prevent formatting conflicts with MegaLinter,
which also runs Prettier. Define the hook as a script since system hooks
don't support running multiple commands.
