feat(sdk-node)!: drop lazy-loading of jaeger exporter

[pichlermarc]

Which problem is this PR solving?

A whole bunch of bundlers (at least vite, and rollup, likely many more) are failing to build when @opentelemetry/sdk-node is used. The reason for it is that we try to lazy-load @opentelemetry/exporter-jaeger if present, which we've marked as deprecated for a long time now. That exporter has been superseded by @opentelemetry/exporter-trace-otlp-http et al. since Jaeger now has native support for OTLP

This PR removes the lazy-loading in favor of the OTLP exporter, which remains fully supported.

Though deprecated, the Jaeger exporter will continue to be published from this repo until we mark @opentelemetry/exporter-trace-otlp-http as stable.

Fixes #4297

I'll leave this open for a bit longer to give everyone some time to voice concerns, if any.
If there's no opposing comments I'll merge this in on Monday. 🙂
