{.github/workflows,action.yml}: run windows in unattended mode

Add the `--unattended` flag when running the action on windows-based
machines. This allows the action to properly connect on windows machines
that do not have full GUI support under the hood (e.g., for the current
batch of `windows-11-arm` runners).

Fixes #180
