Investigate why postCreate and postStart scripts are hit and miss

[agardnerIT]

The postCreate and postStart scripts seem to sometimes fire and sometimes not.

This results in the services not running and manifests as a gRPC connection error. You'll notice because no docker pods are running and the ports have no associated services. Running docker ps will be empty.

The temporary fix (until this issue is looked at) is to manually run both scripts:

.devcontainer/postCreate.sh
.devcontainer/postStart.sh
