Wrong description about openCV version

Description

From "https://pkg.go.dev/gocv.io/x/gocv#section-readme" The Description talks about version 4.5.4:

You can use make to install OpenCV 4.5.4 with the handy Makefile included with this repo.

The Makefile includes still the old version 4.5.3:

# OpenCV version to use.
OPENCV_VERSION?=4.5.3
