Fix dependency version conflict
Fix dependency version conflict

This fixes a version conflict indirectly related to the `mailerlite/mailerlite-api-v2-php-sdk` package.

We replace this dependency by our own modified fork in order to be able to update its own dependencies.

See the changes that have been brought to the fork for more context and info:
