[nit] RUF005 says to prefer unpacking over concatenation, we may want to comply in those places?

[shiftinv]

we considered RUF005 back then: #935 (comment)
At least in my limited testing, unpacking is really only faster than concatenation when there are 3+ collections involved (and slower with only 2), which isn't the case in any of the current RUF005 violations, but there's definitely a readability benefit in many cases, so let's re-enable it.
