chore: remove helpers.php

[Log1x]

I've removed this on every project I've made with Sage 10 up to this point as I can't really find a reason I'd use a messy global function over using a method inside of a Composer, a trait, or my own class.

Thoughts?

can we get the README and docs updated as well?

I usually create functions inside helpers (not more than 5 per project) and I am interested to know deeper what would be the best approach. Maybe add a section in the documentation after this removal?

I understand that the simpler one is to add a method inside app/View/Composers/App so it's available to all the views.
In the case of a class/trait, where would we require/instantiate the class in the current folder structure? In bootstrap/app.php? In config folder?

I understand it would be the same concept of acf composer which creates classes inside Blocks, Fields and Options folders and instantiate the classes through acf composer.
