Add installation step to add the bundle in the config

[dazz]

I ran into an error and it was fixed by adding the bundle.

This might not happen to newer projects with recipes enabled.

Thanks @dazz, let's just add a note to make it clear this step may not be required.

I am curious why it didn't auto-add for you. No flex in your project?

Hey @kbond, yes it's a rather old project which gets updates, but is never fresh set up so it's missing some features, like Symfony Flex.
