[`ruff`] Treat `yield` before `break` from a terminal loop as terminal (`RUF075`) (#25447)

## Summary

Closes #25378.

Extends the yield-before-return terminal check to also cover
yield-before-break, but only when the enclosing loop is itself in a
terminal position. break exits the innermost loop, so a yield right
before it has no cleanup code after it in that case.

## Test Plan

mdtest passes for fallible-context-manager.md across the new and
existing cases
