[BUG] - Unclear --signed-tx-file argument to governance verify-poll

Other Any other topic (Delegation, Ranking, ...).

Summary
The cardano-cli governance verify-poll has --signed-tx-file FILE argument. The corresponding helptext states:

Filepath to a signed transaction carrying a valid poll answer.

However the FILE value can be both signed tx file and tx body. The verify-poll command checks the "required signers" listed in the tx, not the actual signatures.

Expected behavior
The argument should be named e.g. --tx-file and command help should state that the argument accepts both signed tx and tx body.
