[ML] AIOps: Fix log rate analysis alert details page embedding. (#186371)

## Summary

Fixes the log rate analysis embedding in the O11y alert details page, a
regression caused by #180969.

The refactor in the linked PR moved the data fetching for the histogram
chart higher up in the component tree and it was then missing from the
embedded variant.
