[fix] Fall back to current minor when next minor branch doesn't exist (#7286)

## Summary
- When the next minor branch (e.g., `core/1.35`) doesn't exist yet, fall
back to current minor (`core/1.34`) for patch releases instead of
failing
- Fixes the weekly release workflow failure when ComfyUI is on version
1.33.x and `core/1.34` doesn't exist yet

## Test plan
- [x] Tested locally with version where next minor exists (1.33.5 →
finds core/1.34)
- [x] Tested fallback when next minor doesn't exist (1.34.7 → falls back
to core/1.34)
- [x] Tested error case when neither branch exists
