Call "terraform init" before "bbl lbs" / "bbl outputs"

• use image with latest bbl and Terraform versions: https://github.com/cloudfoundry/bosh-bootloader/blob/main/ci/dockerfiles/deployment/Dockerfile
• temporarily deployed to "appruntimedeployments" repository until https://hub.docker.com/r/cfinfrastructure/deployment is updated again

This is a temporary change to test the updated bbl docker image: https://github.com/cloudfoundry/bosh-bootloader/blob/main/ci/dockerfiles/deployment/Dockerfile

One alternative to adding terraform init everywhere might be to set DELETE_TERRAFORM_PLUGINS to false in the bbl-up jobs. See this PR in cf-d-c-t for more details.

Doing so would mean that we only have this terraform init call in one place, if/when we eventually look to rip it out. On the flip side though, adding these ~70MB plugins all over relint-envs is going to slow down pulling and pushing that resource.

When this bbl commit is released, we can probably remove our own terraform init calls again:

My approach with saving the terraform plugin doesn't appear to be working..
