SVN is deprecated in Xcode, problematic for font casks

[vitorgalvao]

Based on a post by @vsivsi.

In the latest versions of XCode, svn is deprecated. This means the svn-based font casks do not install correctly on fresh Catalina installs.

brew install svn solves it for now.

svn is still available via the CLT's, though:

FYI: Homebrew/brew#7781 and Homebrew/brew#7814

Basically, brew tests will now report subversion not installed for Catalina as svn on macOS 10.15 is unreliable.
