In macOS 11, HomeBrew installs swiftlint under /opt/homebrew, which is not
in the default path that Xcode seems to use. So we include the PATH
to contain:
- /usr/local/bin:
Where HomeBrew installs 'swiftlint' in macOS 10.15 and earlier
- /opt/homebrew/bin:
Where HomeBrew installs 'swiftlint' in macOS 11
