Adds component type names for prometheus and Zipkin exporters to be used in SDK health metrics.

Both Zipkin and Prometheus are explicitly supported in the SDK specification, so it makes sense to add those.

Generate semconv/v1.36.0 (open-telemetry#7032)
5e212ba 
Resolve open-telemetry#7030 

This generation fixes the following:

- The `semconv/weaver.yaml` file is moved to the
`semconv/templates/registry/go` to [fix the
generation](open-telemetry#7030 (comment)).
- Deprecated enum `var`s are no longer generate.
- The deprecation of the previous `OSTypeZOS` (`z_os`) conflicts with
the replacement (`zos`).
- This matches all other generations where deprecated types are not
generated and the migration docs identify users need to upgrade when
upgrading packages.
- Fix metric description rendering to handle multi-line metric
descriptions.
- Fix filter of deprecated metrics in weaver configuration (see
open-telemetry/weaver#847).

The release notes for v1.35.0 are included as we do not plan to add a
package for that release and it includes breaking changes being released
here (i.e. `az.namespace` and `az.service_request_id`)
