Re-posing the below from #95

The deposit page is rather sparse at the moment & it's time to address that. I'm opening this issue to track and ideate over what to include:

• [ ] Congrats artwork
• [ ] Change colour scheme on progress bar & handle post-deposit status à la #94
• [ ] Client suggestions (It looks like there are going to be 4 at launch, namely: Lighthouse, Nimbus, Prysm, Teku and I'd like to randomise the order in which they appear.) There should be links out to the various clients.
• [ ] Show validator deposits on Eth2 explorers Beaconscan & beaconcha.in

All of the above was implemented long ago
