6.5 RC with symfony flex

[DevertNet]

Please describe the feature you would like to see implemented.

Hello,

is it possible to use 6.5 RC with the Symfony Flex template?
That would make testing much easier, especially since there will probably be a few more RC relaeses for 6.5.
This would also make it easier to pre-test new versions in the future.

I have posted this here rather than in Slack as I suspect several people are asking this question.

With composer create-project shopware/production:6.5.0.0-dev you can create a new Shopware Project with Symfony Flex.

Any new RC can be updated by running composer update
