fix(stepfunctions-tasks): incorrect policy generated for athena start…

…queryexecution task (#25911)

The policy was originally adjusted in #22314 to use `formatArn()` to account for other partitions. However, there were no tests for these policies before this fix, so it was not identified that the policy would start getting incorrectly generated without being able to act on the resources inside a bucket.

Closes #25875
