msi: use loose versioning for openvpnserv2 in Renovate

By default, Renovate uses semantic versioning, which
assumes versions follow the format X.Y.Z. However,
openvpnserv2 uses 4-part versions like 1.4.0.1 and 2.0.0.0.

This commit tells Renovate to use versioning=loose,
which accepts versions with any number of dot-separated segments
and compares them correctly.
