Re-roll lockfile

[NullVoxPopuli]

In this PR: https://github.com/emberjs/ember-test-waiters/pull/455 it was discovered that the lockfile has a lot of unneeded things in it.

This PR:

• upgrade dev node + npm, via volta
• deletes the lockfile
• re-generates the lockfile
• updates the ci-build.yml GH Action workflow to accomodate the above changes

Looks like doing this ends up requiring most of the changes from: https://github.com/emberjs/ember-test-waiters/pull/455 -- so I'm going to close this PR, and propose #455 be next.
