[Vampire]

To do the .main.kts and .yaml change together, we can do config like

packageRules: [
  {
    groupName: "actions-checkout",
    matchPackageNames: [
      "actions/checkout",
      "actions:checkout___major"
    ]
  }
]

But the range update is not happening in a good way so far, so the proper configuration should be figured out for that first.
