Subject: [PATCH] Add support for Composer version 2

Composer version 2 has `composer-plugin-api` version 2. This commit updates the version constraint to `^1 || ^2` so we can support both composer versions.

See https://php.watch/articles/composer-2 for more changes in API. Empty methods \SLLH\ComposerVersionsCheck\VersionsCheckPlugin::deactivate() and \SLLH\ComposerVersionsCheck\VersionsCheckPlugin::uninstall() are added to make it compatible both versions.
