Suppress vLLM v1 executor sleep/wake log messages (#4011)

Browse source 
* Suppress vLLM v1 executor sleep/wake log messages

Add HideLoggingMessage filters for vllm.v1.executor.abstract logger to
suppress repetitive sleep/wake INFO and WARNING messages that spam training
output when UNSLOTH_VLLM_STANDBY is enabled. The existing filter at line 275
handles the legacy vllm.executor.executor_base path; this adds coverage for
the v1 engine path used by vllm 0.11+.

* [pre-commit.ci] auto fixes from pre-commit.com hooks
