ssl_ca is ignored for bytebase_instance.data_sources

Configuring the CA certificates for RDS instances does nothing to get them configured. Have to use the web UI to add them.

Example:

resource "bytebase_instance" "my_dev_instance" {
  resource_id        = "my_dev_instance"
  title              = "my_dev_instance"
  environment        = bytebase_environment.dev.id
  engine             = "POSTGRES"
  list_all_databases = true
  data_sources {
    id   = "admin-conn"
    type = "ADMIN"
    host     = "my_dev_instance.dk2lk3430se.us-east-2.rds.amazonaws.com"
    port     = "5432"
    username = "bytebase"
    password = "*******"
    ssl_ca   = file("${var.aws_region}-bundle.pem")
  }
}

Even if I delete the existing connection info in the UI and rerun terraform it will be recreated but without the CA certs.

Start by tracing how the bytebase_instance resource handles data_sources and the ssl_ca attribute during Terraform apply. Reproduce the example configuration, then verify that the resulting connection includes the CA certificate rather than requiring the web UI; done means the configured CA is preserved after recreation.
