roachtest: re-enable acceptance/bank/zerosum-splits

PR cockroachdb#34080 which intended to skip `bank/zerosum-restarts`,
mistakenly skipped `bank/zerosum-splits` instead.
(As `zerosum-restarts` had been skipped already prior)

There was no reason to skip `zerosum-splits`, so this commit
re-enables it.

Release justification: non-production code changes

Release note: None
