Also handy

As with all things Homebrew, the source path has changed over the years.

$ ln -s /opt/homebrew/Cellar/llvm/17.0.6_1/bin/clang-format /opt/homebrew/bin/clang-format
$ ln -s /opt/homebrew/Cellar/llvm/17.0.6_1/bin/clang-tidy /opt/homebrew/bin/clang-tidy

brew --prefix should be used to generate the base directory, currently /opt/homebrew.

Naturally, the exact LLVM version will change frequently.
