PR Summary

• Adjustment of Build Workflow
  The setting in our project build process was tweaked to now include 'intl' and 'fileinfo' which are useful tools for handling internationalization and file data respectively.

• Changelog Update
  Our change record now includes a new entry for the resolution of Issue Add Image validation rule #670 - the addition of an 'Image' validation rule. The 'Image' validation rule can verify image files according to specific criteria.

• Updated Project Dependencies
  The project has been updated to use additional packages and modifications that aid in its operation. These include psr/http-message for handling HTTP messages in a standardized way; a suggestion for ext-fileinfo which is useful for handling and manipulating file information; and an upgrade to version 3.0 for yiisoft/translator package, a key tool in the application used for translations.

• Addition of the 'Image' Rule
  We have integrated the new 'Image' rule into our application's rule set. This rule checks the validity of image files. This change is also reflected in our project documentation under the "File rules" section.

• Enhancement of Test Mechanisms
  We have adjusted the way our application testing is conducted with the modification of method signatures in both RuleTestCase.php and CompareTest.php to ensure better and more accurate tests. New test image files were added to increase the range of tests for the new 'Image' rule.

• Tests for New 'Image' Rule
  We've included a separate comprehensive set of tests specially dedicated to the new 'Image' rule to ensure its optimal functioning.
