Updates two of our release scripts to make them work correctly. 1. post-13-homebrew.sh: Homebrew changed their default branch to main recently, see https://github.com/Homebrew/homebrew-core/pull/228218. 2. post-15-conan.sh: This is a small quality of life improvement for macOS release managers. ### Are these changes tested? Yes. I ran them myself during the 21.0.0 post-release tasks. ### Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service.
