PR #16866 renamed the `decode` argument in gettransaction to `verbose` to make it more consistent with other RPC calls like getrawtransaction.

However, if I understand correctly, it inadvertently overloaded the "details" fields when `verbose` is passed.

The result is that the original "details" field is no longer returned correctly, which seems to be a breaking API change.
