chore: use public repository metadata

[Soengkit]

Summary

• update package.json#repository.url from the legacy git:// GitHub URL to a public git+https URL
• keep the package metadata accessible to npm consumers and registry tooling without relying on the deprecated Git protocol

Validation

• checked the current npm metadata for connect-browser-sync@2.1.0
• parsed package.json and confirmed repository.url is git+https://github.com/schmich/connect-browser-sync.git
• git diff --check
• git ls-remote https://github.com/schmich/connect-browser-sync.git HEAD
