[main][CI] update nightly VLLM_ENGINE_READY_TIMEOUT_S (vllm-project#11530)

### What this PR does / why we need it?
This PR standardizes the `VLLM_ENGINE_READY_TIMEOUT_S` environment
variable to `3000` across various nightly end-to-end (e2e) test
configurations for DeepSeek and GLM models. This ensures consistent
engine startup timeout limits across single-node and multi-node test
environments.

### Does this PR introduce _any_ user-facing change?
No, this change only affects internal nightly e2e test configurations.

### How was this patch tested?
Tested via existing nightly e2e test suites.
