Describe the Bug

If you call directus.items('my_collection').readOne(id) and id happens to be an empty string, the request will return an array of objects matching directus.items('my_collection').readMany().

Either the typing of readOne is not correct or calling readOne with an empty string should fail.

interface IItems<T extends Item> {
    ...
    readOne(id: ID, query?: QueryOne<T>): Promise<OneItem<T>>;
    readMany(query?: QueryMany<T>): Promise<ManyItems<T>>;

If you ask me, I'd like readOne to always behave the same and not fall back to readMany behavior. But that's a breaking change and would require a guard in readOne which is a high cost just for the sake of consistency. If we were to rely on typescript we could extend IItems to have the appropriate return types for readOne.

At the very least, I propose to create a PR for the docs at https://docs.directus.io/reference/sdk/#read-single-item. This behavior should be documented somewhere. But I'm waiting for your judgment on how readOne should behave.

To Reproduce

Use the directus sdk and call directus.items('my_collection').readOne(''). The http request will go to <directus-location>/items/rh_members/ and return an array.
