P-551 Workspace dependencies for Parachain

[BillyWooo]

Nice. LGTM.
Small question: when should we use std feature like this litmus-parachain-runtime = { workspace = true, features = ["std"] } ? How could we know it? Is there any other feature we need to take care?

You only need that for the node compilation, we know that becuase there's no default-features = false in the original toml.
I believe all necessary features are already taken care of :)
