Enumeration PlutusLanguageVersion

The Cardano ledger tags scripts with a language that determines what the ledger will do with the script.

In most cases this language will be very similar to the ones that came before, we refer to these as 'Plutus language versions'. However, from the ledger’s perspective they are entirely unrelated and there is generally no requirement that they be similar or compatible in any way.
