By default Docs will not be on the dsfr theme but
on the generic theme. La Gaufre is part of the dsfr
theme and is removed from the generic theme.
Same for the "beta" keyword and the "proconnect"
buttons.
If we are with the DSFR theme, we need to add the
proconnect button to the homepage.
We add an option in the cunningham theme to
display the proconnect section instead of the
opensource section.
