fix: improve support for new requireHooks update (#2313)

* fix: make sure appDir exists before running requireHooks

* fix: run prebundledReact if appDir exists in conf

* fix: use ExperimentalConfigWithLegacy for appDir

* fix: set cache to manual and env as optional

* fix: prettier

* fix: update appDir check

* fix: styled-jsx solution for 13.5

* test: add styled-jsx to included files test

* test: added next latest to i18n for testing

* fix: remove i18n for wp

* fix: use requireHooks based on next -v and appDir

* fix: remove fs-extra

* fix: add semver to handler

* fix: try to import semver

* fix: testing something new

* fix: reset

* fix: add back useHooks

* fix: test updates + remove preRender update

* test: add useHooks

* refactor: use existing resolveModuleRoot function instead of module.createRequire

* fix: remove 13.5
