When source_type = "all" (default or explicitly set), if I only have helm or manifest config args, query fails with invalid configuration

[cbruno10]

Describe the bug
When source_type = "all" (default or explicitly set) in my kubernetes.spc, if I run a query, I receive an error since Kube is looking for a cluster to connect to:

connection "kubernetes" {
  plugin = "kubernetes"
  
  manifest_file_paths =  ["/Users/cbruno/kube/deployments.yaml"]
  # Defaults to "all"
  #source_type = "all"
}

> select * from kubernetes.kubernetes_deployment

Error: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable (SQLSTATE HV000)

If I then change source_type = "manifest", then the query works:

Steampipe version (steampipe -v)
v0.20.9

Plugin version (steampipe plugin list)
v0.22.1

To reproduce
See above

Expected behavior
If source_type = "all", even if I don't have a Kube cluster configured, the helm and manifest information should still be loaded

Additional context
Add any other context about the problem here.

Maybe source_type should be changed source_types and it would accept an array of values, e.g., source_types = ["helm", "manifest", "deployed". With this pattern, a user could load any combination of sources.
