support marketplace kit (#2833)

Description:
Adds marketplace kit support. Installing alternative app stores doesn't appear to work with an adhoc build so need to test in the wild. Internal users only.

The final version should use our current link handling logic, this direct approach is just to validate it works.

Steps to test this PR:

With an iOS 17.4 device or simulator with internal user flag enabled access https://chrisbrind.rocks/testing/ and click on the marketplace URL and you should get a toast. Check that tapping COPY copies the URL into the pasteboard.
Try the above where any of the conditions are false (e.g. older version of iOS, internal user flag off, etc). Nothing should happen when clicking on the link.
