The `pub package cache` step in composite-flutter-setup keys its cache
on a hash of the pubspec.yaml files found under dev/, examples/, and
packages/, but omits the root workspace pubspec.yaml. The root pubspec
pins the versions of all transitive dependencies, so a pub roll that
only touches the root, leaves the hash, and therefore the hash key,
unchanged. This is exactly what happens on pub package rolls like
flutter#189760.

When that happens the cache still hits and restores a stale pubspec.lock
over the freshly checked-out one. At that point, the following `flutter
update-packages` then fails when run with `--enforce-lockfile`, since
the lock file we just restored from cache no longer matches the pinned
versions in the checked-out root pubspec.yaml, which breaks the Tree
Analyze step tree-wide until the cache is manually invalidated.

We now include the root pubspec.yaml in the hash so that a packages only
roll changes the cache key, forcing a fresh package resolve rather than
restoring a stale lock.

Fixes: flutter#189825
