add sealedsecret-bitnami-v1alpha1 to master-standalone

[dshuvar]

When I use kubeval with sealed-secrets I see error like below:

ERR - storage/aws-secret.yaml: Failed initializing schema https://kubernetesjsonschema.dev/master-standalone/sealedsecret-bitnami-v1alpha1.json: Could not read schema from HTTP, response status is 404 Not Found

Could you please help add add sealedsecret-bitnami-v1alpha1 to master-standalone?

I almost sure that master-standalone/secret.json has backward compatibility with sealedsecret-bitnami-v1alpha1
because in background incside bitnami-labs/sealed-secrets used bitnami-labs/kube-libsonnet
