Can't see who thumbed up on a conversation

[xdamman]

Conversations can be a powerful way for communities to make decisions (in fact, I'd even argue they should be renamed to "Proposals").

But we can't see who approve them.

We should be able to click on them to see who reacted (and their reaction)

E.g. https://opencollective.com/commonshub-brussels/conversations/proposal-eur900-for-wifi-installation-4pz3gg6b
