Update credits for new site

[stomar]

The GitHub repository and/or its "Issues" page should be linked in the credits.

Proposal (not perfect; links are italic):

This website was generated with Ruby using Jekyll. It is proudly maintained by members of the Ruby community. Please contribute on GitHub or contact our webmaster for questions or comments concerning this website.

rubyidentity.org is unreachable. Does anyone know who's behind this website?

In any case, I propose getting rid of this link (the one set on "by members of the Ruby Community") while keeping the text (which sounds great), and providing a dedicated page on the wiki (such as Team) were we document things. This reduces the number of links in the footer, ensure there is both only one direct contact (the "webmaster") and one distant "contact" (the github repository). What do you think?

Yes, please.
