fix(perlnavigator): Add cmd and installation instructions for perl navigator (#3106)

* Add cmd and installation instructions for perl navigator

The prior instructions only included building from source. This includes installation of the perlnavigator from npm and a default command. Should make the perlnavigator simpler to install and configure.

* Update perlnavigator.lua
