Support asdf in ns doctor #6061

Is your feature request related to a problem? Please describe.

I use asdf to manage my Ruby and Node versions. Unfortunately this currently breaks ns doctor, which means iOS builds fail during the CocoaPods test. The reason is that ns doctor performs the CocoaPods test in the /tmp folder -- but the asdf configuration is in the project folder.

Describe the solution you'd like

The ns doctor command could check for asdf and if it's present, get the configured Ruby version for the project, and create a .tool-versions file in the CocoaPods test project directory that specifies this version.

See referenced PR below.
