PR Summary

• Update of PHP Version in Workflow The workflow settings have been tweaked to allow it to operate across multiple versions of PHP - 7.4, 8.0, 8.1, and 8.2. This should make our application more robust and compatible with a wider range of environments.

• Additional Issue Handler in Psalm Configuration In our code-base quality verifier, we have added a new issue handler - 'MixedAssignment' - but we've set it to be suppressed for now. It's like having a guard watching out for a specific type of code irregularity, but not raising alarms yet.

• Code Annotation Adjustment in ArgumentException We made cleanliness adjustments in the ArgumentException area of our program by removing unnecessary annotations. Less distractions for our developers during coding.

• Description and Annotation Refinements in the Injector File In one of the critical parts of our program (Injector), we polished the description of a function's outcome and swept away additional annotations relating to 'MixedAssignment' error levels. It helps our code to not only look cleaner but also makes its functionality easier to understand.

Note: Any other changes made in this PR are minor and do not have a significant impact on how our application works.
