[Bug]: `mason new` does not start an interactive session

[lucaferranti]

I'm using

❯ chpl --version
chpl version 2.1.0 pre-release (44b3e6b437)
  built with LLVM version 14.0.0

Just calling mason new should start an interactive session

❯ mason new --help
Usage:
    mason new [options] <project name>
    mason new                    Starts an interactive session

however this does not seem to be the case

❯ mason new
A package name must be specified

A similar issue for mason init, the documentation says it should start an interactive session, but running it only creates a Mason.toml.

Looking at masonNew.chpl, I see a proc beginInteractiveSession defined, but that is not called anywhere as far as I can tell.
