Updates archive again (elastic#209828)

fix elastic#158318

Upgrading from `8.18.0` to `9.1.0` is not a supported upgrade path, nor
is upgrading from `8.19.0` to `9.0.0`.

These awkward upgrade paths have the unfortunate side effect that
migrations integration tests running against certain data archives fail
during backports, depending on the versions they're being backported
from and to.

This PR updates an archive to `8.19.0` in the hope that it will not
cause failures on backports from main to 9.0.0
