Fix node-experimental setup

[mydea]

After digging into this, there were a few problems here that came together:

1. Conflicting versions of Sentry SDK - there was both @sentry/node in an older version, as well as @sentry/node-experimental installed. We only need @sentry/node-experimental
2. We have a bug with our node-fetch support which seems to be breaking when this is not available instead of silently ignoring this. I opened a PR to hopefully fix this here: fix(node-experimental): Make node-fetch support optional getsentry/sentry-javascript#9321, for now I bumped node via volta to v18 so this works.
3. Most importantly, you were calling the otel tracing setup before initializing sentry, which mucked up all the instrumentations etc. I removed this (from the www files) to make this work
4. The manual instrumentation code in service-green was incorrect as far as I can tell, it failed for me. I rewrote this to work (hopefully xD)

With this, I seem to get correct traces now, I believe. Error capturing is also working I think, Sentry actually helped a lot to debug some of the issues on this list 😅

Thank you @mydea.

This is guarded via environment variable and should not be a problem - please correct me if I'm wrong.

It happened in the www files that actually was calling app.js, I think?

Oh yeah! Good catch, thank you.
