[CI] Upgrade vLLM to 20250920 (c60e613) and address config break (#3067)

### What this PR does / why we need it?
Bump main to
vllm-project/vllm@c60e613

- Updated imports in `vllm.config` to
`vllm.config.model`(vllm-project/vllm@aed1687)
vllm-project/vllm#25252

- Refactored `vllm_ascend/sample/sampler.py` to use string values for
`logprobs_mode` instead of the `LogprobsMode` enum, simplifying logprobs
mode handling and improving compatibility with recent vLLM changes
(vllm-project/vllm@aed1687)
vllm-project/vllm#25252

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
CI passed


- vLLM version: v0.10.2
- vLLM main:
vllm-project/vllm@6d8246a
