Title: Add platform requirements to composer.json

I tried to run codeception on a machine without mbstring extension and got some errors, so I added the respective platform deps to `composer.json`:

- json
- mbstring

There might be other required php extensions, but those are the ones I could spot quickly.

Cheers!
