Update findOne method to use new document structure

[Bellian]

Description

I messed arround with this for way too long now.
the documentation is just wrong it seems...

Without the as any I get the following type errors:

Argument of type '<S extends { strapi: Core.Strapi; }>({ strapi }: S) => { findOne(documentId: string, params?: object): Promise<{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }>; }' is not assignable to parameter of type 'WithStrapiCallback<PartialWithThis<Partial<CollectionType> & Generic>>'.
  Type '<S extends { strapi: Core.Strapi; }>({ strapi }: S) => { findOne(documentId: string, params?: object): Promise<{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }>; }' is not assignable to type '<S extends { strapi: Core.Strapi; }>(params: S) => PartialWithThis<Partial<CollectionType> & Generic>'.
    Type '{ findOne(documentId: string, params?: object): Promise<{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }>; }' is not assignable to type 'PartialWithThis<Partial<CollectionType> & Generic>'.
      Type '{ findOne(documentId: string, params?: object): Promise<{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }>; }' is not assignable to type 'Partial<Partial<CollectionType> & Generic>'.
        The types returned by 'findOne(...)' are incompatible between these types.
          Type 'Promise<{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }>' is not assignable to type 'Promise<AnyDocument>'.
            Type '{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }' is not assignable to type 'AnyDocument'.
              Type '{ id: ID; documentId: string; locale?: string; name?: string; createdAt?: DateTimeValue; publishedAt?: DateTimeValue; slug?: string; theme?: JSONValue; updatedAt?: DateTimeValue; }' is not assignable to type '{ documentId: string; id: number; }'.
                Types of property 'id' are incompatible.
                  Type 'ID' is not assignable to type 'number'.
                    Type 'string' is not assignable to type 'number'.ts(2345)

Just boiling down to a ID type mismatch..
In the typings this type is just not up to date:

export type AnyDocument = {
    documentId: string;
    id: number;
} & {
    [key: string]: any;
};

Which should be:

export type AnyDocument = {
    documentId: string;
    id: number | string;
} & {
    [key: string]: any;
};

Also this.getFetchParams does not exist if you do not also modify the method.. so you need to access this from the super object.

Thank you, @Bellian!

There was a small typo (probably a copy/paste error) + I added comments for super.

The PR is now approved, merged, should be live on docs.strapi.io in a few minutes, and will be mentioned in the next weekly snapshot release.
