✨ Paseo config (#317)

## What?
- Add paseo chain spec
- Refactor all chain specs

## Why?
- To start our paseo testnet
- To avoid duplicating code and improve readability

## How?
- Split chain specs into files depending on their relay chain
- Remove unused live chain specs, keep the json files at ./chain-specs

## Testing?
- Run with zombienet each chain spec and check if we produce blocks
