Convert stored properties into computed properties

[galijot]

This PR addresses a compiler error in Xcode 15.0 Beta, which states:

Stored properties cannot be marked potentially unavailable with '@available'

Since use of such properties is inhibited through a compiler error, I've simply replaced the stored properties marked as unavailable with computed properties that are returning the same result they're returning now.

Thank you!

Wouldn't it have been better if instead of

public var allowTap: Bool { return true }

to do this:

public var allowTap: Bool { self.singleTapGestureRecognizer.view != nil }

It would stay consistent with the new API instead of being a computed property which in essence is a constant?

Since the property is annotated with @available(*, unavailable, renamed: "isUserInteractionEnabled"), accessing it results in a compiler error: 'allowTap' has been renamed to 'isUserInteractionEnabled', because of which a value of this property is irrelevant.

(I believe) It's just kept to make upgrades from older package versions easier to perform, since it's not really obvious that isUserInteractionEnabled does the same thing that allowTap used to do.
