### What?
`payload.collections` was improperly typed.
This doesn't seem to work: (the type is `{}`)
```
collections: {
[slug: CollectionSlug]: Collection
} = {}
```

However, this does:
```ts
collections: Record<CollectionSlug, Collection> = {}
```

Additionally, the same fix applied to `Permissions`,
`PolymorphicUploadField['admin']['sortOptions']`,
`PolymorphicRelationshipField['admin']['sortOptions']`
