Remove help wanted text from README

Despite some great work done in the last couple of months, nobody showed a strong motivation to take over this project.

I want to thank @hkdobrev for his hard work as he helped me lot in closing issues and fixing bugs. Silex is now compatible with Symfony 4 and that's going to help a lot in migrating projects.

I still strongly believe that Symfony 4 is a better alternative and that there is nothing unique anymore in Silex.

Forking is still an option if someone wants to take over of course.
