[bitnami/thanos] Thanos ruler don't support TLS on grpc

Name and Version

thanos 0.36.1

What architecture are you using?

amd64

What steps will reproduce the bug?

The querier can be configured to use TLS for GRPC client connections by adding the following configuration:

query:
  enabled: true
  grpc:
    client:
      tls:
        enabled: true
        autoGenerated: true

This configuration forces the querier to use TLS when calling GRPC endpoints. However, there is currently no way to activate a similar TLS configuration for the ruler component. For comparison, the storegateway component allows TLS configuration for its GRPC server using the following settings:

storegateway:
  enabled: true
  grpc:
    server:
      tls:
        enabled: true
        autoGenerated: true

The issue is that we need a way to enable TLS for GRPC connections on the ruler component, similar to how it's implemented for the querier and storegateway.

Are you using any custom parameters or values?

No response

What is the expected behavior?

GRPC TLS setup for ruler like for storegateway.

What do you see instead?

dialing connection: context deadline exceeded: connection error: desc = \"transport: authentication handshake failed: tls: first record does not look like a TLS handshake

Additional information

Arguments like grpc-server-tls-cert, grpc-server-tls-client-ca and grpc-server-tls-key are fully supported by Thanos ruler : https://thanos.io/tip/components/rule.md/#flags.
