+Check if a binary is already available in the system PATH.

+This is the simplest "provider" - it doesn't install anything,
+it just discovers binaries that are already installed.

+Usage: on_Dependency__install_using_env_provider.py --dependency-id=<uuid> --bin-name=<name>
+Output: InstalledBinary JSONL record to stdout if binary found in PATH

+Environment variables:
