Add as many EVM compatible chains as possible

[gagdiez]

We right now have abstracted the EVM chains, now we just need to add more than Ethereum and Base

• BNB

• Avalanche

• Polygon

• Zksync

• Add in docs that we now support all those chains (add all missing chains as well)

@gagdiez @matiasbenary needs help with BNB contract uploading for this one.
