Update the citybik.es website!

[Altonss]

Two points should be updated on the website @eskerda (I didn't find a repository for it) 😄:

• The android app that is still linked in the black bar and does not exist anymore in the playstore should be removed (or replaced with a working app like https://github.com/francoisfds/BikeSharingHub
  
  

• The android app https://github.com/francoisfds/BikeSharingHub could be added to the list of projects! (maybe replace the app https://github.com/bparmentier/OpenBikeSharing or at list be more visible than it, because it is not developped since 2017 AFAIK)

• Remove Google Analytics for GDPR compliance :)
