Feral v0.2.3-rc.4

ci(release): use TheMrMilchmann/setup-msvc-dev (ilammer action was 404)

The previous attempt referenced ilammer/msvc-dev-cmd, which no longer exists
as a repository — GitHub failed every matrix job at "Set up job" (action
resolution happens for all steps regardless of their `if:`), so Linux and
macOS regressed too. Swap to TheMrMilchmann/setup-msvc-dev@v3.0.2 (confirmed
to exist) to load the MSVC environment for the Ninja-based Vulkan build.
