Use actual openURL method on iOS

[ASalavei]

Fixes the following error when calling URIHandler_openUri on iOS 18:

The caller of UIApplication.openURL(_:) needs to migrate to the non-deprecated UIApplication.open(_:options:completionHandler:). Force returning false (NO).

@igordmn , FYI, the bug targeted to 1.7.1

Need to build skiko and upgrade version then, it's critical due to apps likely not able to pass submission checks.

How about deleting this API completely instead? Why does a multiplatform graphics abstraction need to offer an API to open a URL?

[elijah-semyonov]

You are absolutely right, it shouldn't be there, it's a forgotten leftover. We fix it first, remove later.

[ASalavei]

Good that we spotted it. I believe we will discuss removal soon.
Anyway, the API seems to be going through a deprecation process, and there are some more of them.
