**BREAKING:**
Improves type-safety of collection / global slugs by using `CollectionSlug` / `UploadCollectionSlug` and `GlobalSlug` types instead of `string` in these places:
Adds `UploadCollectionSlug` and `TypedUploadCollection` utility types
This also changes how we suggest to add an upload collection to a cloud-storage adapter:
Before:
```ts
azureStorage({
collections: {
[Media.slug]: true,
},
})
```
After:
```ts
azureStorage({
collections: {
media: true,
},
})
```
