Add credits to beaconcha.in

[Buttaa]

Hi, butta from beaconcha.in 👋🏻

Happy to see that beaconcha.in was forked and contributed to! 🥳
However, it looks like the fork is missing credits to the original repo in the footer 😢

Could this please be added?

@Buttaa We are sorry about that, will add the reference.
Should we leave the original copyright © or add link to the master repo?
