This PR enables the chainSpec_v1 class for the polkadot-parachian.
The chainSpec is part of the rpc-v2 which is spec-ed at: https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/chainSpec.md.

This also paves the way for enabling a future chainSpec_unstable_spec on all nodes.

Closes: #5191

Why is the type needed now in contrast to before?

I think I've hit the autocomplete by mistake :D No longer needed since I was able to obtain the same by moving the initialization to the substrate builder

Nice one, with this refactor now all users of polkadot-sdk gets the entire rpc v2 API without having to use their own rpc extensions for it.

I would like to re-phrase this as:

The substrate-service-builder now includes the entire rpc v2 API. The chainspec API was previously defined as rpc extension where for instance chains would need to enable it explicitly for it to be enabled which isn't the case anymore
