feat: add chiado (#4530)

## Issue Addressed

N/A

## Proposed Changes

Adds the Chiado (Gnosis testnet) network to the builtin one.

## Additional Info

It's a fairly trivial change all things considered as the preset already exists, so shouldn't be hard to maintain.

It compiles and seems to work, but I'm sure I missed something?
