This PR hardens the url() function in packages/cli-kit/src/public/node/notifications-system.ts by adding validation for the SHOPIFY_CLI_NOTIFICATIONS_URL environment variable. It ensures that the URL is valid and uses the https: protocol, falling back to the default Shopify CDN URL otherwise. This mitigates the risk of loading notifications from insecure or malicious sources. Unit tests have been added to verify this behavior.

This change ensures that the URL used for fetching CLI notifications,
whether default or provided via the `SHOPIFY_CLI_NOTIFICATIONS_URL`
environment variable, is a valid HTTPS URL. This prevents potential
loading of malicious content from insecure or invalid sources.

- Validates `SHOPIFY_CLI_NOTIFICATIONS_URL` using `globalThis.URL`.
- Enforces `https:` protocol for notifications.
- Falls back to default Shopify CDN URL if the provided URL is invalid or insecure.
- Adds unit tests to verify the hardening.
