Describe the bug
I am attempting to generate event names for the ruby semantic conventions library but it is failing as the command can not be found. The process is described in https://github.com/open-telemetry/weaver/blob/7e9d00bc050c4055b87ce42f2857e2f6e63f1a02/docs/codegen.md#understanding-filters

To Reproduce
Steps to reproduce the behavior:

1. Add the following to your weaver config

  - template: "stable_attrs.j2"
    filter: >
      semconv_grouped_events({
        "stable_only": true,
        "exclude_deprecated": true,
        "exclude_root_namespace": ["url", "network"]
      })
    application_mode: each

2. Run weaver generatiom
3. Observe error

Expected behavior
To be able to get all events like I can for metrics.

Additional context
It appears the functionality is missing from https://github.com/open-telemetry/weaver/blob/7e9d00bc050c4055b87ce42f2857e2f6e63f1a02/defaults/jq/semconv.jq
