refactor(workflows): avoid using cached states for release instances (#…

…9137)

- Renamed `no_cached_disk` input to `need_cached_disk` in `cd-deploy-nodes-gcp.yml` to clarify its purpose.
- Adjusted conditional logic for cached disk usage based on event types (release vs. non-release) in `cd-deploy-nodes-gcp.yml`.
- Removed the environment strategy matrix from `sub-deploy-integration-tests-gcp.yml` to simplify the workflow configuration.
- Enhanced comments for better clarity on caching and environment handling across workflows.
