Gossamer generated raw spec with empty BABE authorities

[EclesioMeloJunior]

Describe the bug

Using the same human-readable specification such as https://gist.githubusercontent.com/danforbes/b246640cbedd1107ff412d5d25851058/raw/815fa77feee103e518a41a3f593c5d4442d14db6/gistfile1.txt gives an empty BABE authority set.

Running the following commands the gossamer node will start but will not produce blocks because the current BABE authority set will be empty.

gossamer build-spec --genesis-spec ./human-readable.json --raw --output ./spec.json

And then

gossamer --chain ./spec.json

However, using the Polkadot binary to generate the raw specification from the human-readable one and using the raw spec to start a gossamer node the BABE authority set will contain authorities.

Let's de-prioritise this for now and focus on supporting the latest runtime. Let's consider removing this functionality entirely and have a discussion about it.

Is this essentially a duplicate of #2417?

[EclesioMeloJunior]

No, this is related to a likely problem while building the key value map with infos from the json spec

[danforbes]

Iceboxing this because we will probably de-prioritize our ability to generate/build specs for now.
