Consider adding other snowflake-using FOSS products

Follow-up of !18 (merged) where @meskio wrote:

This MR brings an interesting question. Should we list all apps that have snowflake support, if so we might need to add OnionShare, Briar and Brave too. I think we should.

But adding all of them with the current design of cards will take a lot of space. We could eider make smaller cards for everything or keep TorBrowser and Orbot (being more general purpose) bigger and have a list of others in smaller cards. But I trust there are others that are better than me on UX.

For me it will be ok if this gets merged as it is. But I would like that we map a way forward to add the other snowflake capable apps there as well.
