PY_VER placeholder not defined/updated correctly on Windows

What happened?

I have used the turtle minimal example json file in order to test menuinst, on my Windows 10 computer, using the latest menuinst version available from conda-forge (2.1.1) and I ended up with a new Python N.A menu, which did not seem completely right

• the turtle example file uses: "menu_name": "Python {{ PY_VER }}",
• the general placeholders documentation says that PY_VER should be Python major.minor version in PREFIX, so probably something else than N.A

Some quick digging showed me that placeholders is defined in ./platforms/base.py

    def placeholders(self) -> Dict[str, str]:
        """
        Additional placeholders added at runtime:
        - MENU_ITEM_LOCATION -> *MenuItem().location

        Subclasses may extend this dictionary!
        """
        return {
            "BASE_PREFIX": str(self.base_prefix),
            "DISTRIBUTION_NAME": self.base_prefix.name,
            "BASE_PYTHON": str(self.base_prefix / "bin" / "python"),
            "PREFIX": str(self.prefix),
            "ENV_NAME": self.env_name,
            "PYTHON": str(self.prefix / "bin" / "python"),
            "MENU_DIR": str(self.prefix / "Menu"),
            "BIN_DIR": str(self.prefix / "bin"),
            "PY_VER": "N.A",
            "HOME": os.path.expanduser("~"),
            "ICON_EXT": "png",
        }

But the default value of PY_VER is probably never updated (correctly). At least not in the part of
./platforms/win.py that I have checked

    def placeholders(self) -> Dict[str, str]:
        placeholders = super().placeholders
        placeholders.update(
            {
                "SCRIPTS_DIR": str(self.prefix / "Scripts"),
                "PYTHON": str(self.prefix / "python.exe"),
                "PYTHONW": str(self.prefix / "pythonw.exe"),
                "BASE_PYTHON": str(self.base_prefix / "python.exe"),
                "BASE_PYTHONW": str(self.base_prefix / "pythonw.exe"),
                "BIN_DIR": str(self.prefix / "Library" / "bin"),
                "SP_DIR": str(self._site_packages()),
                "ICON_EXT": "ico",
            }

It's quite possible I have not checked the right places, but this looks like a possible explanation
