Add mason hello world tutorial

[ reviewed by @arezaii ]

This PR adds a hello world example to the mason docs that shows the
most basic form of installing a mason package and using it in user
code. The tutorial uses the HelloWorld mason package and calls the
only function that it provides: helloChapelFriends().
