Manually Craft CreateSnapshotRequest to fix BwC Test (#57661)

* Manually Craft CreateSnapshotRequest to fix BwC Test

We can't use the high level create snapshot request any longer
since we changed some of its default parameters in `8` and those
are not understood by older versions like `7.4`.

Closes #57650
