Fix Broken Index Shard Snapshot File Preventing Snapshot Creation (#41310) (#41473)
* The problem here is that if we run into a corrupted index-N file, instead of generating a new index-(N+1) file, we instead set the newest index generation to -1 and thus tried to create `index-0`
   * If `index-0` is corrupt, this prevents us from ever creating a new snapshot using the broken shard, because we are unable to create `index-0` since it already exists
   * Fixed by still using the index generation for naming the next index file, even if it was a broken index file
* Added test that makes sure restoring as well as snapshotting on top of the broken shard index file work as expected
* closes #41304
