Fix issue with bwc tests running wrong cluster versions (#58063)

We were previously configuring BWC testing tasks by matching on task
name prefix. This naive approach breaks down when you have versions like
1.0.1 and 1.0.10 since they both share a common prefix. This commit
makes the pattern matching more specific so we won't inadvertently
spin up the wrong cluster version.
