Updated dependency to fix Symfony/contracts issue.

Good evening,

I ran into the following error when attempting to deploy my project to PROD:

After Googling the issue it seems like the problem lies with the symfony/contracts dependency. It should actually be symfony/translation-contracts.

Thanks!

This is not a fix, as symfony/translations already depends on those contracts. We have symfony/contracts as a dependency for the real loose bound contracts, specifically the Event Dispatcher.

The error you have is technically impossible, as symfony/contracts explicitly indicates that it replaces symfony/translation-contracts, so both cannot be installed at the same time.

I would recommend:

1. Upgrade your Composer to the latest version
2. rm -rf vendor
3. composer update
