Docs: brew install opencv@3 no longer works on macOS (formula removed from Homebrew) #6091
Description
Description of issue (what needs changing)
The installation docs for MediaPipe still recommend: "brew install opencv@3" This formula has been removed from Homebrew. Only brew install opencv (which installs OpenCV 4.x) is available. As a result, the documented command fails for macOS users. The docs should either: •Update to brew install opencv (if OpenCV 4 is supported), or •Direct macOS users to use MacPorts (Option 2 already in the docs), or •Recommend Bazel/pip installation paths instead of relying on Homebrew.
Clear description
- Current docs suggest installing OpenCV 3 with Homebrew. 2. Homebrew removed the opencv@3 formula, so the command no longer works. 3. This blocks new users from following the official installation guide on macOS.

I can open a PR after confirmation from maintainers whether: OpenCV 4 via brew install opencv is officially supported, or macOS users should switch to MacPorts / Bazel / pip paths.
