Update version check for Mountainsort5 in is_installed method

This commit updates the version checking logic in the is_installed class method to allow the use of Mountainsort5 versions 0.3 and newer. Previously, only version 0.3.x was accepted, but testing has shown that version 0.4.1 is also compatible. The warning message has been updated to reflect this change.
