[Security] Harden notifications URL validation#8029
Conversation
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.
