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`) ## [`v1.36.0` semantic convention release notes](https://github.com/open-telemetry/semantic-conventions/releases/tag/v1.36.0) <div data-pjax="true" data-test-selector="body-content" data-view-component="true" class="markdown-body my-3"><h3>🚩 Deprecations 🚩</h3> <ul> <li><code>os</code>: Adds the 'deprecated:' tag/attribute to the <code>z_os</code> enum value of <code>os.type</code>.

This addresses part of #1725. Specifically the stdout portion.
The use case for this is before the change there is no way to stop or flush the batching SpanProcessor created in these convenience functions. After this change a user that creates a pipeline via the
NewExportPipeline()orInstallNewPipeline()can also close the batching functionality.This does not change Jaeger, because it would break compatibility with its internal batcher, which would be removed as part of #1799.
This does not change Zipkin or Prometheus, as those are already exposed in this way.
