Merge bitcoin/bitcoin#25231: ci: Install documented packages for "Win64" CI task

3ffc190 ci: Install documented packages for "Win64" CI task (Hennadii Stepanov)

Pull request description:

  This minor change has the following benefits:
  - it follows the [documented](https://github.com/bitcoin/bitcoin/blob/master/doc/build-windows.md#building-for-64-bit-windows) way for modern Ubuntu distros (this CI task uses jammy)
  - it makes package installation time shorter as no need to install the `g++-mingw-w64-x86-64-win32` package
  - (not directly related to this repo) in https://github.com/bitcoin-core/gui-qml Qt 5.15.3 (but not 5.15.2) build system goes [wild](https://cirrus-ci.com/task/6231535933194240) otherwise
