The current version of the extension tries to download the Windows
binary files for lua-language-server like this:
`lua-language-server-3.9.3-win32-x64.tar.gz`

The [Windows binary
files](https://github.com/LuaLS/lua-language-server/releases) are only
released as zip archives, so it will fail to get the required files.


This pr changes the following:
- Add check for Windows specific zip archive
- Add check for Windows specific .exe executable

Release Notes:

- N/A
