[javascript] discontinue use of deprecated APIs

[pichlermarc]

Hi all - this PR contains updates to documentation discontinuing the use of deprecated APIs. As discussed in #6396 this is in preparation of the upcoming SDK 2.0.0 release, but uses only features that are available in the currently latest release 1.30.1/0.57.2 for now.

I will follow up with 2 other PRs for

• assets/js/tracing.js (edit: refactor(tracing): discontinue use of deprecated APIs #6418)
• actually lifting all JS docs to 2.0

Notable changes:

• BasicTracerProvider#register() will be removed to allow for better tree-shaking
  • this was replaced in the docs by manually registering the propagator that would've been registered by BasicTracerProvider#register()
  • NodeTracerProvider#register() is still available in 2.0, therefore docs using it remain unchanged
  • WebTracerProvider#register() is still available in 2.0, therefore docs using it remain unchanged
• *TracerProvider#addSpanProcessor() was replaced by a spanProcessors constructor option, which is available since 1.28.0
  • changing this required some re-ordering in the docs as exporters used to be instantiated later
• I updated dependencies in the serverless docs to ensure that all of these features are available.

LGTM from a copy edit perspective. Let's get another set of eyes on this from @open-telemetry/javascript-approvers. Thanks!

This file should be the snippet of FrontendTracer.ts.
But it seems it is already out-of-date, so I won't block this PR.

I've created the issue open-telemetry/opentelemetry-demo#2080 to follow-up on the Demo repo.

@pichlermarc - so this is gating on open-telemetry/opentelemetry-js#5148? I'm going to mark this as blocked and "request changes" to ensure that this doesn't get merged ahead of time by mistake.

I think the two API PRs can be merged once they're approved based on the tracking issue. So I don't think they need to be blocked. But @pichlermarc can confirm.

removing use of deprecated APIs (can be merged immediately as the replacements for these are already present in the latest release)

Thanks for double-checking. 🙂 open-telemetry/opentelemetry-js#5148 is not required before this PRcan be merged. All the features used here are available in the latest 1.x version of the SDK.

After this PR, I will follow up with another one that will actually lift the docs to 2.0 (that one will then be blocked by open-telemetry/opentelemetry-js#5148) 🙂
