`chain_spec_path` should support `https`

[michalkucharczyk]

For tests with db_snapshot stored in cloud, the raw chain_spec must be kept together with the snapshot. It would be good to store it in the cloud in the same bucket as db_snaphot. Would be good if chain_spec_path supported the https and zombienet automatically downloaded spec file (as it downloads db_snapshot file).

is db_snapshot also uses https?
