refactor(ci): Move bundle size check to a parallel job

Creates a new reusable workflow, 'bundle-size.yml', to handle the bundle size check.

This check is now run in a separate job in the main 'orchestrator.yml' workflow, parallel to the 'e2e' job. This optimizes the CI pipeline by allowing the E2E tests to start as soon as the bundle is published, without waiting for the size check to complete.
