Script ToJSON instances serialises the full script

[ghost]

There used to be no orphan instance for ledger Script so we (Hydra)
provided our own. This newly introduced instance overlaps with our own
which would not be a problem, as we are fine using upstream instances,
but for the fact the serialisation is lossy as cardano-api only
serialised the hash of the script.

Note this is an alternative to #4130 which is less principled (still has orphan instance in a place there should be none) but easier to integrate.

@Jimbo4350 I am trying to update my PR to address comments you made on @ch1bo 's PR #4130, but not sure what's the best approach. There's currently a Shelley.Orphans module in the cardano-cli, do you want me to create a Babbage.Orphans module that would contain this script instance?

Looks reasonable to me.

Oh I see I should have approved #4223 which is the version rebased on the master branch.

[Jimbo4350]

LGTM, can you squash the commits?

[ch1bo]

@Jimbo4350 would need to open another branch on origin for that. I have squashed & rebased on the master PR. We would love to get it after master also onto release/1.35 but not sure what the policy is.

[ch1bo]

This change was merged now on master. Shall we close this and cherry-pick the commit from master onto release/1.35 instead?

Looks like this has already been merged into the release branch. Closing.
