Versioning and stability > Signal lifecycle: image still uses "experimental" status, and some statuses missing

[chalin]

Maturity levels are defined in https://github.com/open-telemetry/oteps/blob/main/text/0232-maturity-of-otel.md, and include Stable, Development, and more -- such as Alpha, Beta, etc.

If you visit https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/versioning-and-stability.md#signal-lifecycle you'll see:

• [ ] The image in that pages still uses "Experimental". That should be updated to "Development". /cc @tedsuo
• [ ] Only "Stable" and "Development" are described. Shouldn't this section mention all of the permitted statuses, such as "alpha", "beta", etc? By providing other statuses, it will give our OTel docs link targets -- e.g. Rust signal statuses are in alpha and beta at the moment.
