chore: update RILT chain spec and boot nodes (#633)

## fixes KILTprotocol/ticket#3400

RILT is booted from scratch, resulting in a different genesis
state/wasm. To add more nodes later on, we need to update the chain's
specifications.

The chain spec is generated by calling: 

`docker run kiltprotocol/kilt-node:1.13.0 build-spec --chain=rilt-new
--raw > nodes/parachain/res/rilt.json`

The deprecated bootnodes are also updated.
