Blender LTS: Download + Release notes CMS scripts

This patch contains 2 scripts that will help with LTS releases

create_download_urls.py

    This python script is used to generate the download urls which we can
    copy-paste directly into the CMS of www.blender.org.

    Usage: create_download_urls.py --version 2.83.7

      --version VERSION  Version string in the form of {major}.{minor}.{build}
                         (eg 2.83.7)

    The resulting html will be printed to the console.
