Attributes missing from filter output

[thompson-tomo]

Describe the bug
When i use the semconv_grouped_attributes filter, not all the attributes from semantic conventions are being included in the output. The options are defined at https://github.com/open-telemetry/weaver/blob/7e9d00bc050c4055b87ce42f2857e2f6e63f1a02/docs/codegen.md

To Reproduce
Steps to reproduce the behavior:

1. Clone semconv repo
2. Alter the attribute_namespace template so the filter is semconv_grouped_attributes
3. Generate documents
4. Observe the feature flag page is missing the feature_flag.provider_name attribute
5. Add a debug output to the template ie {{ ctx.attributes }}
6. Observe attribute is not in the output

Expected behavior
The weaver output (see attached) has the feature_flag.provider_name attribute

Additional context
PR where i noticed the issue is: open-telemetry/semantic-conventions#3836

Issue appears to be documentation related as they appear when you set the ignore_code_generation_annotations setting to true which is not listed in the examples showing the usage of all the options in https://github.com/open-telemetry/weaver/blob/2ccfcaf7d4c4e7240dfc6afd3f49c4c41f7674c9/crates/weaver_forge/README.md#jq-filters-reference
