924f25f6fc bench: Match ConnectBlock tx output counts (monlovesmango)

Pull request description:

  There turned out to be a mismatch in the tx output counts which caused 'ConnectBlockMixedEcdsaSchnorr' benchmark to run slower than 'ConnectBlockAllEcdsa' and 'ConnectBlockAllSchnorr'. This commit makes the tx output counts uniform across all benchmarks.

  This commit also renames the 'taproot_tx' variable to 'tx' to reflect that this variable represents a general tx and not just a taproot tx.
