Generate semconv/v1.36.0 (#7032)

Resolve #7030 

This generation fixes the following:

- The `semconv/weaver.yaml` file is moved to the
`semconv/templates/registry/go` to [fix the
generation](https://github.com/open-telemetry/opentelemetry-go/issues/7030#issuecomment-3074916061).
- 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
https://github.com/open-telemetry/weaver/issues/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`)
