Allow importing any file from the payload packages like it was in V2

[CherryDT]

In Payload V2, if there was some module you did not export but I needed it nonetheless, I was just able to do something like import { CheckboxInput } from 'payload/dist/admin/components/forms/field-types/Checkbox/Input', of course on my own risk that it could break on updating. This allowed deep customization and fast development.

In Payload V3, something like import { MoveItemsToFolderDrawer } from '@payloadcms/ui/dist/elements/FolderView/Drawers/MoveToFolder' fails:

Module not found: Package path ./dist/elements/FolderView/Drawers/MoveToFolder is not exported from package /mnt/c/Users/david/proj/***/node_modules/@payloadcms/ui (see exports field in /mnt/c/Users/david/proj/***/node_modules/@payloadcms/ui/package.json)

Yes I know this is unsupported. But without it, development will be 5-10x slower for me, which is a huge drawback compared to V2.

Never mind, I just had to remove dist/.
