I tried downloading and installing Moodle 4.4 this morning from the Zip file https://download.moodle.org/download.php/stable404/moodle-4.4.zip, but encountered an error that MariaDB version 10.6.7 is required, as specified in admin/environment.xml (see screenshot below). However, I then downloaded the Windows installation file Moodle installer package for Windows. It has a different environment.xml file which only requires MariaDB 10.4. The Release Notes specifies MariaDB 10.6.7, but the installation worked OK for me on 10.4, although I haven't tested it in operation very much.
This is either a bug in the Moodle installer package for Windows, or an error in the documentation.
