### What this PR does / why we need it?
Triton-ascend occasionally encounters compilation errors, which is a
known issue in triton-ascend 3.2.0. However, we want to use the official
version rather than the development version, so we only changed the
triton-ascend version in the Dockerfile and added a FAQ to explain this
issue.
