[CI] Quick fix mooncake for nightly-ci (#4028)

### What this PR does / why we need it?
Since we have upgraded to CANN 8.3rc1, we will no longer use the
privately maintained Mooncake repository, but instead use the official
release released by Mooncake:
https://github.com/kvcache-ai/Mooncake/releases/tag/v0.3.7.post2 .

Next step: this is only a temporary solution. We will integrate mooncake
into the vllm-ascend base image later for easier use. see
https://github.com/vllm-project/vllm-ascend/pull/3989
### Does this PR introduce _any_ user-facing change?

### How was this patch tested?

- vLLM version: v0.11.0
- vLLM main:
83f478bb19
