feat(hyper-js): add types for type exposure

[PritishBudhiraja]

Type of Change

• New feature

---

Description

Added types support for loadHyper and added descriptions with examples. So via code editor it can look good.

let hyperPromise = loadHyper("pk_snd_12342", {
  options: {
    customBackendUrl: "https://api.abc.in",
  },
});

---

How did you test it?

Via locally using the build and using the same in my demo store and converting the file from .js to .ts and errors and warnings were coming when I was using the req types.

---

Usage Notes

Yes it's a breaking change so we will be bumping our major version for this. Folks who are using the .js one won't face issue but .ts one might need to integrate properly with types.

---

Version Update

Will bump the version accordingly based on discussion.
