Pull request overview
Updates the repository’s versioning policy to explicitly require telemetry stability guarantees for stable artifacts, aligning this repo’s expectations with the OpenTelemetry specification’s versioning/stability guidance.
Changes:
- Expands the versioning section to cover both compatibility and telemetry stability requirements for stable artifacts.
- Clarifies that configuration changes are breaking by default (with limited exceptions), and that telemetry changes are breaking unless permitted by the spec’s semantic conventions stability rules.
- Refreshes links and wording to directly reference the upstream OpenTelemetry Java and specification versioning documents.

With a few minor exceptions we've maintained telemetry stability throughout the 2.x minor releases.
I think we have the experience and migration pathing figured out to officially document and be even more strict going forward.
This is coming one way or another:
