Add spec for integration testing infrastructure

[uglide]

Note

Low Risk
Documentation and site navigation only; no runtime or test code changes.

Overview
Adds docs/integration-testing.md, a full spec for how Jedis integration tests work: the redislabs/client-libs-test Docker setup, docker-compose / Makefile workflows, endpoints.json and Endpoints.getRedisEndpoint, TLS via TlsUtil, unit vs integration naming (*IT for new tests), and how CI (test-on-docker vs integration) maps to TEST_ENV_PROVIDER.

CONTRIBUTING.md is shortened: community support points to Redis Discord instead of Google Groups; the long inline Docker/Makefile testing section is replaced by a link to the new guide plus explicit *IT / unit-test rules. The “adding commands” subsection is removed from contributing.

mkdocs.yml adds a Development guide nav section linking Contributing, Integration Testing, and benchmarks.
