Would be great to have a config option to disable the "version" check of the composer.json of ComposerMustBeValid.

• [Architecture] Composer.json is not valid:
composer.json: The version field is present, it is recommended to leave it out if the package is published on Packagist.

So if we develop a package which must have a <version> in its composer.json we can disable the check of the version, but not the whole ComposerMustBeValid check, to reach 100% in ARCHITECTURE but still get the composer.json checked.

The composer validator has now an option to disable version check. composer/composer#8802

However, that could work only when using ComposerV2.

But maybe we should configure level to raise issue ($errors, $publishErrors, $warnings)
