Running from non-root directory issue

[luongvo]

Hi @garriguv,

I'm working on a KMM project, and the KMM project is inside a sample folder.

• The ios module of the KMM project is located at sample/ios.
• The Dangerfile of the iOS project is at sample/ios/Dangerfile.

Running the Danger with SwiftFormat produces a File not found error as below. The cause is while danger-ruby-swiftformat returns the list of swift files with the full path from the root dir, e.g. sample/ios/fastlane/Constants/Constant.swift, including sample/ios, SwiftFormat joins them with the current working dir /Users/runner/work/kmm-templates/kmm-templates/sample/ios/.

Run bundle exec danger --danger_id=danger_ios

I was able to workaround this by running Danger from within the ios directory and adding a symlink hack on CI `cd ios; ln -s . ios
