Fix dev branch not syncing issue

[ghost]

Overview

The issue was the altered chain spec, the chain spec that was used to launch a fresh parachain was from v0.0.4-dev tag and from that commit to the latest there has been several changes to specs/arrakis.json. Due to that, when trying to sync with the remote node, local node was producing different genesis hash.

Another issue was that spec/arrakis.json was in plain format, when it should be raw. And chainType also should be Live instead of Local (although for a syncing node, it's not a big deal, but if we were to run a collator, Live chains need to insert keys, etc.)

In the future, we should always maintain the chain spec in raw format and make sure to never alter it, except when the chain was reset.

Test

To test this fixes the issue:

// checkout to this branch `fix/sync-issue-dev`

docker run -v $(pwd):/data freeverseio/laos-ownership-node:3132e53c232562764268175af39df70aa4540ed8 --chain data/specs/arrakis.json

this runs the latest binary with the new arrakis.json and you should be able to sync with the remote node.
