licamera: controls: Update ControlList::get() documentation

Browse Source 
The ControlList::get(const Control<T> &ctrl) function has been modified
in commit 1c4d480185 ("libcamera: controls: Use std::optional to
handle invalid control values") to return an std::optional<>, but its
documentation wasn't updated. Fix it.
