PR Summary

• Improved PHP Version Check for MIME Types
  This update includes a bug fix to better handle MIME types depending on the PHP version being used. This will ensure we are using the correct MIME type definitions where needed.

• Updated MIME Types Definition in libmagic
  We've fixed a bug related to the 'libmagic' library, a crucial part of our system which helps detect file types correctly. This was done by including a new type, specifically 'xz' files, and treating them as 'application/octet-stream'. This change expands the variety of file types our system can correctly identify and handle.

Was this the only version check which was accidentally changed?

Since there were 3 checks in the original PR: https://github.com/yiisoft/yii2/pull/19936/files

[rob006]

For FileValidatorTest it is still there:
https://github.com/yiisoft/yii2/blob/master/tests/framework/validators/FileValidatorTest.php#L550

MimeTest was removed in #19951
