Fix CI: remove --no-dev from framework-tests composer install

The framework-tests project (Naktibalda/codeception-mezzio-tests)
references Mezzio\Tooling\ConfigProvider in its config/config.php,
but mezzio/mezzio-tooling is a require-dev dependency. Using
--no-dev skips its installation, causing the ConfigAggregator to
fail with "class cannot be loaded".
