chore(deps)!: upgrade to otel v2.0.0 (#791)

* chore(deps): upgrade to otel v2.0.0

this is a breaking change

closes #790

* Update packages/opentelemetry-resource-util/package.json

Co-authored-by: Aaron Abbott <[email protected]>

* chore(ci): remove Node.js 14 from CI matrix

fix(pkg): rename exporter packages to align with ownership

feat(node): update required Node.js version to 16

refactor(tracing): remove unused Tracer import and update resource detection method

feat(ci): add support for upgrading to OpenTelemetry v2 branch

style(tracing): adjust formatting for better readability in configurations

feat(ci): modify branch triggers for CI workflow

chore(revert)

feat(resource): improve resource detection by refactoring to use detectResources

* Fix changes that were made to instrument snapshot tests

* remove commented lines

* remove OT_VERSION from user agent strings since there is no public API to get it

Adding it at build time won't work since the peerDependency may be a different version at runtime.

Some possible alternatives:
- read it defensively from "@opentelemetry/core/build/src/version.ts"
  even though it's not exported from index and may disappear
- try to read it from package.json which may fail with bundling and is
  clunky

* Revert "remove OT_VERSION from user agent strings since there is no public API to get it"

This reverts commit ca1b573.

* Try to lazily get version from package.json or fallback to "unknown"

* Make sure that ATTRIBUTE_NAMES statically contains all possible keys

* simplify detector.test.ts

* fix instrumentation quickstart

* Restore the original dep versions for @opentelemetry/semantic-conventions

* remove some unused code

BREAKING CHANGE: drops compatibility with OpenTelemetry SDK 1.0 which changes some types and may require some updates. For more information on the changes and migrating to 2.x, see https://github.com/open-telemetry/opentelemetry-js/blob/v2.0.1/doc/upgrade-to-2.x.md.
