Why the actual OpenCV version 4.1.1 is different from the document at OpenCV 4.5.0 (with CUDA)?

Hi,
The OpenCV package is different between Jetpack 4.6 and docker. In Jetpack 4.6, it is 4.1.1 without CUDA. In docker it is 4.5.0 with CUDA.

What is docker here? Is it supported by Jetson nano? If it is supported, why Jetpack 4.6 does not include OpenCV 4.5.0 with CUDA?
Thanks
