This PR was squashed before being merged into the master branch (closes #8569).

----------

Lots of automated migrations to Symfony Flex structure

Almost all of these changes need a check if the paragraphs surrounding the code block still make sense, but at least, it is a start.

I skipped the Best Pratices and Create Your Own Framework guides. Both of these need to be completely revisited.

Also, lots of other (configuration, bundles, controller and services) guides need to be checked carefully.

Please review and merge quickly @symfony/team-symfony-docs
