      TLDR: Update the CollectionBulkLoader to build indexes in the foreground in server releases prior to 6.0.

      One of the improvements made in SERVER-57432 was to change the index build method during initial sync from hybrid to foreground. This has been shown to improve initial sync latency in our performance test suites. Additionally, foreground index builds do not consume additional disk resources that hybrid index builds require to handle concurrent user writes.
