Issue Description:

As reported by Aaron Sky on the forums:

https://forums.swift.org/t/annotate-objective-c-block-type-with-ns-swift-ui-actor/55437

This method ought to be imported as taking and return a @MainActor function type, but doesn't seem to be:

@import Foundation;

typedef void (^FooAction)(void) NS_SWIFT_UI_ACTOR;

@protocol Foo
@property (nonatomic, nullable) FooAction didDoFoo;
- (void)doFoo;
@end

Hi @rjmccall, I'm a part of a software development cohort. I would like to use this issue as my first contribution to swift repo. Which area can I begin in?

Unfortunately this issue has already been fixed by #70693, sorry for the confusion!
