Why is this an expect now? The pallet is also usable without manager origin.
It returned BenchmarkError::Weightless before.

I think that error is meaningless.

Same as:

polkadot-sdk/substrate/frame/treasury/src/benchmarking.rs

Lines 121 to 126 in 06debd0

let origin =
T::SpendOrigin::try_successful_origin().map_err(|_| BenchmarkError::Weightless)?;
let beneficiary = T::Lookup::lookup(beneficiary_lookup.clone()).unwrap();
#[extrinsic_call]
_(origin as T::RuntimeOrigin, value, beneficiary_lookup);

It was not part of the benchmark(#[extrinsic_call]) code block. Additionally, I believe the original .expect message is more readable. So I reuse it.

What do you suggest?
