Use macOS vz VM type and virtiofs mounts (#42)

* Use macOS vz VM type and virtiofs mounts

Now that the action dropped support for macOS < 13, it makes sense to
rely on macOS native virtualization, hoping to boost performance during
tests. This update also gets rid of the QEMU requirement, which has been
historically difficult to be maintained properly.

* Added CHANGELOG entry

 ## [unreleased]
 
+### Added
+
+- Support for native virtualization provided by macOS Virtualization framework. In detail, now Lima VMs are configured to use `vz` as the VM type and `virtiofs` for mounts. This change leads to significant stability and performance improvements ([#42](https://github.com/douglascamata/setup-docker-macos-action/pull/42)).
+
+### Removed
+
+- Support for QEMU virtualization, which has historically been fragile and hard to maintain. The related `upgrade-qemu` config flag has also been removed ([#42](https://github.com/douglascamata/setup-docker-macos-action/pull/42)).

 ## Inputs
 
-## `inputs.upgrade-qemu` (defaults to `"false"`)
-
-The action, by default, will not try to upgrade QEMU if it's already installed.
-The reason is that installing QEMU takes a considerable amount of time.
-
-If this is set to `"true"`, the action will attempt an upgrade of QEMU to the
-latest version available in Homebrew.
-
 ## `inputs.lima` (defaults to `"latest"`)
 
 The version of Lima to install. This can be any valid version from [Lima releases page](https://github.com/lima-vm/lima/releases)
