Simplify ionic-angular page generator by using code mods toolkit

[kristianmandrup]

Hi @joshuamorony and @devinshoemaker,

I've just created nx-code-mods a Code Modification toolbox/toolkit inspired in large part by update-routing-file.ts and the Nx generator video tutorial by @joshuamorony

Would love to see this page generator simplified by using the toolkit and for the community at large to start using and extending this toolkit instead of writing this low level code mods code from scratch.

Cheers, Kristian
