merge_cc_infos document is missing

Problem description (include actual vs expected text, if applicable):

For previous versions of bazel untili 6.2.0, merge_cc_infos are still documented in cc_common, but in later versions of the doc, the documentation of this function has disappeared. However, the function seems to be migrated to a starlark implemstarlark. Therefore, maybe the doc generation has been broken.

Where do you see this issue? (include link to specific section of the page, if applicable)

On official doc page: https://bazel.build/rules/lib/toplevel/cc_common

Any other information you'd like to share?

It seems like not just merge_cc_infos's doc is missing, but there are other public functions in cc_common undocumented too (according to the list of exported functions at the end of the file), for example:

• merge_linking_contexts
• merge_debug_context

I assume this is because it's entirely starlark where the others still come from java?
