LGTM, nice job! Can you add a test for that, similarly to the other ones here: https://github.com/IntersectMBO/cardano-cli/blob/main/cardano-cli/test/cardano-cli-golden/Test/Golden/Governance/Action.hs

[carbolymer]

The windows CI failure: IntersectMBO/cardano-node#5811 (comment) - we can ignore windows GHA, it's fixed in nix already.

[smelc]

LGTM 🍾 A few typos in the help needs fixing.

[Jimbo4350]

LGTM! Feel free to merge after @smelc approves.

@CarlosLopezDeLara

is not very readable. When you squash commits you need to summarize the changes in those commits in a concise and clear manner.

I also don't know what is happening in 3d8a21f4792c0983b94f493ee064a3203a1c86da.

[smelc]

@CarlosLopezDeLara> those commits should not be here:

Since they have been merged already. I can help you clean this up during our pair programming session 👍
