NEXT-14586 Resolve Symfony 5.1 deprecations

[TheKeymaster]

1. Why is this change necessary?

Since Symfony 5.1 not setting the framework.router.utf8 option is considered deprecated. See:

• https://github.com/symfony/framework-bundle/blob/5.x/CHANGELOG.md#510
• symfony/framework-bundle@f701923

Without these change my plugin tests fail, as the Symfony Deprecation Helper gets mad at me :(.

2. What does this change do, exactly?

Set the utf8 option to be true.

3. Describe each step to reproduce the issue or behaviour.

Run tests that interact with the Symfony/Shopware router.

4. Please link to the relevant issues (if any).

Not entirely sure why the Cypress step fails, but I can not re-run it either. Could someone from you at Shopware do that for me? I do not think that it is related to my change, but with a re-run we would be certain. Thank you guys!

EDIT: Nevermind, I just checked PRs from other contributors as well and it seems like that one test is failing for everyone.

This change is ready for review :)!

Hi @TheKeymaster , thank you for putting in the time to create this pull request 🙂 I've only noticed this after the import unfortunately - would you mind adjusting the changelog entry?
