release: Fix "Verify release" job on macOS GitHub Actions runner (#514)

fixes #513

* Install Subversion explicitly
* Because recent macOS GitHub Actions runner doesn't provide Subversion
by default
* Add support for installing Julia for macOS (Apple Silicon)
  * Because the current `macos-latest` is macOS (Apple Silicon)
