chore: Fixed v22 in versioned tests CI

[jsumners-nr]

When I adjusted our workflow to get around a current runtime bug (#4070 (review)) I did not realize that the workflow is naming coverage files with the explicit version matrix strings. This caused the coverage tool to not find the corresponding coverage files. This PR fixes the problem.

Run https://github.com/newrelic/node-newrelic/actions/runs/28195105982 shows it is all working.
