[FTR - esArchiver] Update delete_unknown_types archive to NOT delet…

…e SO indices (#161936)

## Summary

Part of #161882

Updates the
`test/api_integration/fixtures/es_archiver/saved_objects/delete_unknown_types`
archive:
* deleting `mappings.json`
* updating documents in `data.json`

This way, _esArchiver_ will not delete SO indices and recreate them,
eliminating the odds of the related tests being flaky.
