Move myself alongside the inactive Core team members.

**What a fun ride!** This community is the best I've been working with, full of talented and caring people. I've learnt so much by fixing `@nicolas`-grekas' broken tests or convincing `@fabpot` to ship this Messenger component. I also hope that this modest contribution to the ever-growing list of components inspires others to do the same, give back to an open-source project that enabled me as an engineer to be always more productive and enables us all to focus on solving worlds' problems rather than re-inventing the wheel again.

**I won't have much time for Symfony in the coming 12 months, at least.** For a fair chunk of time already, I have not been able to devote enough time to maintaining and evolving Symfony, and it will remain the same for a little while: I want to focus my energy on building mission-driven startups and it requires my full attention to make them successful. It means I'm not really a Core Team member anymore, so let's make it official so the list can be expanded with great people that have the time I don't.

`@symfony`/mergers thank you so much for your continuous work and care for this amazing project, I know it can only continue to shine. See you in the real world at some conferences, I'm sure ❤️
