Add Docker configurations for PHP 7.4, 8.0, and 8.2

New Docker configuration files have been added to standardize the PHP 7.4, 8.0, and 8.2 environments. Additionally, the "composer.lock" file has been added to the .gitignore file, and the version range of the "orchestra/testbench" dependency in composer.json has been expanded. An .gitattributes file was added to ignore the .docker directory during export.
