Update opentelemetry-js distribution to latest (v1.30.1)

[danopia]

From v1.24.0 towards v1.30.1

semantic-conventions

Upstream now has two different deprecation cycles going on here, and an extra import specifier to select between them.:

• I ended up patching the default import to include all three deprecation cycles since opentelemetry-js has yet to follow either deprecation, while I want to move this library's instrumentations forward to the latest HTTP convenations.
• Don't worry about incubating or not, just import semantic-conventions.js.
• I am deferring HTTP convention changeover to a separate 0.x release so you can take this version without updating your dashboards.

OTLP changes

This includes a pretty large refactor of OTLP exporting:

• Upstream made some sizable exporter consolidation, so I managed to delete our individual custom exporters and instead give the proper node exporter a fetch() implementaion that works nicely with Deno. The final OTLP export javascript is quite clean now - just promises, no callbacks. Nice!
• New OTLP feature: optional export compression (enable with OTEL_EXPORTER_OTLP_COMPRESSION=gzip). Implemented with CompressionStream.
• protobuf exportors are still stripped out. I don't view the amount of additional code worth it. I think if you are at the level where the performance matters, you should be looking forward to deno --unstable-otel instead.
