Downgrade to kustomzie v3.8.8

[devstein]

Description

Discovered by #80 the latest release of KSOPS pinned to kustomize v3.9.0 is broken.

I'm going to merge and make a patch release to un-break master, but I'll do a further investigation into why CI passed and what the root of upstream error is.

Reverting the --enable_kyaml flag fixes the error

kustomize build --enable_alpha_plugins  --enable_kyaml=false
