Update pallet-multisig benches

[ggwpez]

The multisig weights were not updated in #12072 and now the trait does not fit together with the benchmarks; possibly blocking the next release. Build error from paritytech/polkadot#6173:

error[E0046]: not all trait items implemented, missing: `as_multi_create_store`, `as_multi_approve_store`, `approve_as_multi_complete`
