can i make a next-codemod that changes directory from Page to App

[jinhwan7]

Goals

1. new codemode that changes directory from Page to App

Non-Goals

Background

i use nextjs on production for my company
i upgrade version 12 -> 13
i changed directory from page to app
there is little works,
for example Migrating _document.js and _app.js, make page.ts in every routing folder etc
so i want to make it automatically

Proposal

this is my rough plan

1. study how to work the next-codemod package( how do this change code )
2. and change deprecated method like serversideprops
3. migrate __app and _document into layout
   ( i think this 3 can be remove because every person has diffrent _app and _document )
4. change directory name pages -> app
5. change the directory name to the same as file name ex) myPage/main.ts -> myPage/main/page.ts
6. I do other things that I need...

i want contirbute little part of nextjs
