transaction build still takes --constitution-file ; it should be any --action-file

[CarlosLopezDeLara]

This command

cardano-cli transaction build 
...
  --vote-file FILE         Filepath of the vote.
  --constitution-file FILE Filepath of the constitution.
...

should be

cardano-cli transaction build 
...
  --vote-file FILE         Filepath of the vote.
  --action-file FILE      Filepath of the action file.
...

This will become obvious when we are trying to submit any other type of governance action.
