chore: Update deprecations in instrumentation-express/examples (#1842)

* chore: Update express example package.json since it moved repos

This must have moved into contrib a while back

* docs: Modify the install command so that the example runs

Without this, 'npm install' now depends on directories higher than this one.
It does not create a node_modules
and then ts-node does not work.

Looks like the use of workspaces at the repository root interferes with this example,
but this change to the install command gets around that.

* chore: Update instrumentation-express example otel packages to the latest

* chore: Update all deprecations in tracer.ts

Jaeger accepts OTLP now, so the OtlpTraceExporter just works

* update package-lock for (hopefully) desired package.json dep updates

* sync package-lock.json

* sync package-lock.json again (dropping dev:true from '@types/express', why I am not sure)

* add setup script and alternative install

* sync package-lock.json

* bump the express example's dep to the instr-express version in the repo

I also had to manually remove this (vestigial?) entry in package-lock.json
that was breaking 'npm install'.

* signing off on changes
