test: update resolutions.t to expect both original and resolved descriptors
The Berry lockfile resolution fix now correctly preserves both the original
descriptor (as used by packages) and the resolved descriptor (from yarn
resolutions) in the pruned lockfile. This allows packages to find their
dependencies using either descriptor form.
Updated test expectation from:
"is-odd@npm:3.0.0"
to:
"is-odd@^0.1.2, is-odd@npm:3.0.0"
This reflects the correct behavior where yarn combines multiple descriptors
that resolve to the same package into a single entry.
