In iOS 17 and aligned OS versions, `+[NSURL URLWithString:]` now percent-encodes invalid characters
to help create a valid URL, where previously it would return `nil`.

As a result of this new behavior, strings are now made representable as URLs more easily, and so
their URL representations are added to the pasteboard with percent-encoded invalid characters.

Fix by using the new `+[NSURL URLWithString:encodingInvalidCharacters:]` method, which restores
pre-iOS 17 behavior.
