Change the configuration to set the latest PHP version

[tanhongit]

It's necessary to change the configuration so that the latest PHP version will automatically be selected as the default value, not the current 8.2 version.

build:
      context: .
      dockerfile: ./docker/Dockerfile
      args:
          - PHP_VERSION_SELECTED=${PHP_VERSION_SELECTED:-8.2}
          - PHP_VERSION=${PHP_VERSION_SELECTED:-8.2}
