Fix ExtraFS Breaking SharedClusterSnapshotRestoreIT (#58026) (#58040) 

If `ExtraFS` decides to put `extra0/0` into the indices folder
then the previous logic in this test would have interpreted the `0`
as shard `0` of index `extra0` and fail to list its contents (since it's a file
and not an actual shard directory).

=> simplified the logic to use actually referenced `IndexId` for iterating over indices
instead.
