Add bundler version to documentation (Bundler v2.0.1 doesn't work)

[KrzysztofMadejski]

I tried to create account on Decidim but registration screen keeps coming back after clicking "register". Both on Catalan and English version.

Please add gem install bundler -v "~>1.17" to the documentation. Using current bundler (2.0.1) results in an error:

Another problem with setting up decidim: Also default passwords for user & admin & system don't work user@example.org | decidim123456 . The hash for development is set, is it possible that hashing methods depends on gem versions or sth else?

[KrzysztofMadejski]

Regarding original issue: Either specify bundler or update Gemfile as mentioned here: https://github.com/decidim/decidim/blob/master/Dockerfile.design#L14-L18

Sorry for the huge delay @KrzysztofMadejski, we've recently started to address the backlog of issues in using Decidim with Docker.

The bundler version is now >= 2.1.4
