Various updates to EDOT Node.js docs

[trentm]

• Update deep links to opentelemetry-js-contrib due to directory moves in that repo.
• Supported technologies table updates:
  • Point to instrumentation-redis rather than instrumentation-redis-4. The former was accidentally not included, and the latter is now rolled into the former (chore(opentelemetry-node): drop instr-redis-4, it is now consolidated into instr-redis elastic-otel-node#889).
  • Mention some included instrumentations that were missing from this table: connect, cucumber, dns, runtime-node

Fixes: elastic/elastic-otel-node#869
Refs: elastic/elastic-otel-node#889 (review)

@theletterf (/cc @Mpdreamz) what do I do about this docs-build crash?

Error: Uncaught exception while processing file
System.ArgumentException: Markdown elements in the input are too deeply nested - depth limit exceeded. Input is most likely not sensible or is a very large table.

I assume this is because I added a few rows to this existing Markdown table: https://github.com/elastic/opentelemetry/pull/375/files#diff-0beabc8fec73e207ac0aec1a40e68c8a65306e9848186d4a11eda2375825c677R47

FWIW, GitHub renders it fine: https://github.com/elastic/opentelemetry/blob/trentm-edot-node-updates/docs/reference/edot-sdks/nodejs/supported-technologies.md#instrumentations-instrumentations

I look more carefully to see if I made a Markdown syntax error in my changes, but from the error message is feels like I just hit it with too big of a table?

[trentm]

If we need a short term workaround, it would be fine to exclude a few of the rows for less important instrumentations.
