Issue with Conflicting vLLM Version Requirements in lmcache-vllm and lmcache-tests

[bettybaii]

Hello,
I noticed that in the lmcache-tests/prepare_environment.sh, the required version of vLLM is specified as 0.6.2, while in lmcache_vllm/init.py, the required vLLM version is 0.6.1.dev238+ge2c6e0a82. Could you clarify the exact version requirement for vLLM? Is this requirement strict, and will it impact the functionality of both lmcache-vllm and lmcache? Thank you!
