Add support for Relay 13+ generated code by adding $fragmentSpreads support

[Markionium]

Relay 16 generates the following fragment type

export type JobTitleFragment$key = {
  readonly " $data"?: JobTitleFragment$data;
  readonly " $fragmentSpreads": FragmentRefs<"JobTitleFragment">;
};

Our hooks currently only support the older " $fragmentRefs" format that looks as follows.

export type JobTitleFragment$key = {
  readonly " $data"?: JobTitleFragment$data;
  readonly " $fragmentRefs": FragmentRefs<"JobTitleFragment">;
};

This means that when generating code with newer versions of the relay-compiler we can not use those generated fragments with useFragment and will get the following error.

Argument of type 'JobTitleFragment$key' is not assignable to parameter of type 'Readonly<{ " $data"?: unknown; " $fragmentRefs": unknown; }>'.
  Property '" $fragmentRefs"' is missing in type 'JobTitleFragment$key' but required in type 'Readonly<{ " $data"?: unknown; " $fragmentRefs": unknown; }>'.ts(2345)
types.d.ts(32, 5): '" $fragmentRefs"' is declared here.

This PR adds support for both variants which makes useFragment compatible with with Relay types < 13 and Relay > 13.
