Upgrading Sylius plugins to v2.0

[loevgaard]

In the past few months I have seen quite a few issues and PRs with regards to upgrading Setonos plugins to v2.0, therefore I am creating this document/discussion to document what I intend to do with regards to upgrading and I am also very open to input.

• Create a new branch for upgrading and consequently when released, it will be a major release.
• Use new Symfony bundle structure.
• Support Symfony ^6.4 and the latest in 7.x.
• If the plugin has Behat tests, I will try to migrate these tests to PHPUnit tests because I find it a struggle to maintain Behat
• Use Setono/sylius-plugin-pack instead of Setono/code-quality-pack
• Minimize the number of imports needed in the installation process. E.g. if a file like @AcmeSyliusExamplePlugin/Resources/config/app/config.yaml should be included, move those directives to the AcmeSyliusExampleExtension::prepend() method instead.
