Documentation: Fix createRequest unique_ptr

Browse source 
camera->createRequest() function return std::unique_ptr<Request>, then
manipulate Request as std::unique_ptr.
This solve the following error, during compilation:

error: cannot convert ‘std::unique_ptr<libcamera::Request>’ to ‘libcamera::Request*’ in initialization
