3D Slicer version 5.2.2 link

README requires 3D Slicer version 5.2.2:

However, it is not easy to find this specific version. Fortunately, @sandrinebedard pointed me to this link: https://slicer-packages.kitware.com/#collection/5f4474d0e1d8c75dfc70547e/folder/63f5a1888939577d9867aba0

The link could be included directly in README.

It seems to be working also with newer versions, e.g., 5.7.0 in my case:

Hi Jan! The version 5.2.2 comes from me. In April, when I tried to install Slicer, some extensions/modules (ex JupySlicer) made the app crash. In the Internet, there was some forum saying that the most stable version at the time was the 5.2.2 so I have tested on it initially. Since then, I hope some bugs with most recent versions have been corrected. To be tested with most recent versions.
