📚 Description

This PR adds a usePortal prop to ComboboxList.vue in the New York V4 registry.

Why:
Currently, ComboboxList always wraps the dropdown content in a ComboboxPortal, preventing parent components from controlling whether the dropdown is rendered inline or teleported. This causes major usability issues on mobile devices, where teleporting the dropdown often results in poor UX due to the on-screen keyboard and viewport constraints.

What:

• Adds a usePortal prop (default: true) to ComboboxList.vue.
• When usePortal is false, the dropdown content is rendered inline, solving the mobile usability problem.
• When usePortal is true, the previous teleport behavior is preserved.
• No breaking changes; default behavior is unchanged.

I would like to note, that the changes made to the stepper component json files, came from running pnpm build:registry on a fresh clone of the dev branch.
Also, I have not updated the documentation, as I found that it is currently in a weird place as I mentioned in #1316, and needs to be refactor before I would dare contributing to it.

Resolves #1336
