If provisioner fails changeset is stuck preparing

[matt2e]

Steps to repro:

• Break the code in dev_provisioner.go:125 so that provisioning postgres always fails

func provisionPostgres(postgresPort int, recreate bool) InMemResourceProvisionerFn {
	return func(ctx context.Context, changeset key.Changeset, deployment key.Deployment, resource schema.Provisioned) (*schema.RuntimeElement, error) {
		time.Sleep(3 * time.Second)
		return nil, fmt.Errorf("not implemented")

• ftl dev examples/go

Expected:

• changeset should fail and postgres module should show a failure to build
