msix: convert version to valid MSIX format (X.X.X.X)

MSIX packages require versions in strict X.X.X.X numeric format.
Convert Git for Windows versions (e.g. '2.47.1.windows.1' -> '2.47.1.1')
and handle test versions (e.g. '0-test' -> '0.0.0.0') by stripping
non-numeric characters and padding with .0 segments as needed.
