As MDL-73016 set the minimum supported PHP version for Moodle 4.4 and up to PHP 8.1 we can now safely remove this check. As the lang string `errorphp7required` is particular to mlbackend php plugin we are going for direct deletion instead of regular deprecation. Signed-off-by: Daniel Ziegenberg <daniel@ziegenberg.at>
