Add Zeroth EVM to list of chains

[moonlightpark]

Hi Team. 👋

Our newly released wallet will be supporting Zeroth EVM and its testnet (ref: https://scan.zeroth.run/).
Could you add this please to the dropdown in the Explore tab on the dashboard 🙏

ShimmerEVM: eip155:4088
ShimmerEVM Testnet: eip155:14088

Or is that dashboard open source by chance?
If yes, i'd create a PR for that.

Thanks!
