fix: remove dev_dependency flag from google_benchmark

[AlexanderLanin]

google_benchmark cannot be a dev_dependency. Rules for dev_dependency still not understood.... but we need this fix in reference_integration, otherwise it does not work at all.

Pull Request Overview

This PR removes the dev_dependency = True flag from the google_benchmark dependency, converting it from a development-only dependency to a regular dependency in the build system.

[Copilot]

The google_benchmark dependency should include dev_dependency = True since it's only used for benchmarking tests (see src/cpp/tests/bm_kvs.cpp). This follows the same pattern as other test-only dependencies in this file like googletest, rules_python, rust, and score_toolchains_gcc. Without this flag, the benchmark library will be included in production builds unnecessarily, potentially increasing build times and binary sizes.

Suggested change

	bazel_dep(name = "google_benchmark", version = "1.9.4")
	bazel_dep(name = "google_benchmark", version = "1.9.4", dev_dependency = True)
