Update dependency versions in composer configuration

Increases the version constraints for multiple dependencies in both
`require` and `require-dev` sections to ensure compatibility with
newer versions. Updates include `guzzlehttp/psr7`, `vitexsoftware/ease-core`,
`phpunit/phpunit`, `friendsofphp/php-cs-fixer`, `ergebnis/composer-normalize`,
and `ergebnis/php-cs-fixer-config`.

These changes aim to leverage improvements and fixes in the updated
dependencies while maintaining backward compatibility.
