ISSUE_LABE.LABEL no longer exists.

[ac-slater-rr]

The label dimension no longer valid in the issue_label view.

dimension: label {
    type: string
    sql: ${TABLE}.label ;;
  }

Fivetran has normalized the label to a separate table as per their current
ERD here.
Now it should be label_id
and a new view for label

The explores will need to be updated with the new join accordingly.
