Use stable HTTP semantic conventions by default for HTTP instrumentations and update README:

  • http
  • http_client
  • httpx
  • net_http
  • rack
  • restclient
  • excon
  • faraday
  • ethon

Emit warnings for users who have set http/dup or old as the value for OTEL_SEMCONV_STABILITY_OPT_IN.

Set the final transition date as April 15, 2026

Update README documentation for action_pack and sinatra, which depend on rack.

I saw one docs/code mismatch I want to work through before we merge. Otherwise, looks great! Thank you @hannahramadan!
