Update composite identities FF ownership
What does this MR do and why?
This FF does not really have anything to do with CI Platform. I don't have all the context from why it was assigned that way initially. This relates to some work around the pipeline creation process that Pipeline Authoring helped with, but composite identities generally seem to be with AI Framework.

- Ultimately this is related to https://gitlab.com/gitlab-org/gitlab/-/issues/512509#note_2768992108 – the PA work for this is done, but the FF rollout still needs to be handled by the appropriate group
