fix(ci): bump trivy to v0.69.3 to resolve 404 download failure (#9660)

## Summary

- Bumps Trivy from `0.65.0` to `0.69.3` in `.trunk/trunk.yaml`
- Trivy `v0.65.0` was never published — the version scheme jumped from
`v0.26.0` to `v0.69.2`, causing a 404 when trunk tries to download the
hermetic tool binary
- This fixes the "Trunk Code Quality / Check" CI failure seen on #9658
and all other PRs
