test(@angular/cli): verify package group locking under peer updates

Asserts that the update resolver loops correctly prioritize package group expansions before evaluating peer dependencies.

This prevents regression of issue #22654, where specifying a package with a wide pre-release peer range (like @angular/cdk) before a package defining a group (like @angular/core) would resolve group dependencies (like @angular/common) to next-major pre-releases instead of locking them to target group versions.
