chore: reduce duplicate dep installs with 'npm dedupe'

[trentm]

npm ci
npm dedupe

See #2671 (comment) for the motivation for my doing this. From skimming this change I notice that our typescript@5.0.4 usage was being installed in every separate package rather than at the top-level because of some history of how we installed this version and other transitive deps have a dep on a different typescript version.

A surprising result is how much smaller the npm ci result is. This is on a clean checkout and npm ci:

% du -sh *
916M	opentelemetry-js-contrib-after
3.7G	opentelemetry-js-contrib-before

Awesome! Thank you :)

I'll check if we have a similar situation in contrib repo.
