Move conway governance hash to conway hash

[CarlosLopezDeLara]

The hash command needs to be moved one level up in the tree, so that it is not inside governance, but instead just in the top level.

@CarlosLopezDeLara> what about conway governance hash script then? If we move hash anchor-data out of governance, conway governance hash script will be alone in its category. See here:

@smelc my bad, I should have written "move 'governance hash' one level up. This is, it can be a more general purpose command rather than specific to governance.

So the end goal is

cardano-cli conway hash (anchor-data | script)
instead of

cardano-cli conway governance hash (anchor-data | script)
Im updating the description
