Use dev version of Yii Data + increase psalm level to 1

PR Summary

Updated the stability and package version in Composer Configuration The 'composer.json' file, which controls dependencies for the project, has been updated. Its 'minimum-stability' setting was changed to 'dev' allowing us to use packages in their developmental stages. The 'prefer-stable' was set to true, which means we prefer stable versions of dependencies where possible. Additionally, the 'yiisoft/data' package version has been updated.
Adjusted the Error Level in Psalm Configuration The 'psalm.xml' file, controlling a static analysis tool used to identify errors in the code, was changed. It had its 'errorLevel' modified to '1', which represents a stricter level of error checking in our code.
Improved Documentation in Abstract Query Data Reader The 'AbstractQueryDataReader.php' script had been updated to include some annotations related to 'psalm'. This update improves the documentation for developers, especially for the 'prepareHandlers' and 'read' methods.
Removed the Format Values Method The 'formatValues' method was removed from 'Filter/CompareFilter.php'. This indicates a change in how we process and format data in our filters.
