upgrade vllm to v0.7.1 as default version

[kerthcet]

What would you like to be cleaned:

update the default vllm version to v0.7.1

Why is this needed:

we'll add examples to support deepseek v3 & r1.

Line 16 in 9eba500

version: v0.6.0

Is there anything else to do besides update v0.6.0 to v0.7.1 ?

The latest version is v0.7.3. Do we need to upgrade vllm to this version directly?
