fix(next-eslint): .eslintrc.json not being created by next lint on App Router

[devjiwonchoi]

This PR fixes .eslintrc.json not being created after the user runs next lint and selects an option of Strict or Base.
The reason is that the lint check was looking for pages and src/pages only. Added app and src/app to be checked also.

Fixes: #55094
Fixes: #55102
