[KT-52681] Remove unnecessary semicolon after Objective-C @end

Objective-c `@end` doesn't need a semicolon, however KMM exported header
file, for instance:
```
__attribute__((swift_name("KotlinIterator")))
@protocol MyProjectKotlinIterator
@required
- (BOOL)hasNext __attribute__((swift_name("hasNext()")));
- (id _Nullable)next __attribute__((swift_name("next()")));
@end;
```
This creates problems with some code checkers that will not expect it
there, so it seems best to remove it.
