Update Cookiecutter questions

[IgnacioHeredia]

Now that everything will be hosted under ai4os-hub I don't think it makes sense to keep showing users the git_base_url parameter. We can keep having it as a hidden variable though.

I also think something similar for app_version. If you are creating the template you would want always the version to be 0.0.1 right? Does it make sense to be configurable?

Finally, I will add to the help message of project_name that it is the name of the python module. Otherwise, people tend to use very lengthy names that look ugly.

+1 for "ai4o-hub" and git_base_url
for "app_version", I would keep it configurable, someone may consider their version not "0.0.1" if the certain code already existed
to be on the safe side, I put that tin to-do :-)

git_base_url is now "private" so we can change it easily in the future
project_name prompt updated

I leave this open till we decide how to implement the tags in the template

I think, we can close this issue but @BorjaEst , please, have a look to #17
