Expected Behaviour

It would be nice if the extension could recognize files as lua based on a set of configurable extensions.

Actual Behaviour

Currently, it seems to only recognize files with .lua as their extension as lua files.

Reproduction steps

Create a lua file with a different extension, open the file in VSCode. The editor has no idea the file is lua.

通过打开一个扩展名不是 .lua 的 Lua 文件并确认它未被识别，复现 Visual Studio Code 扩展中的行为。跟踪文件语言识别和扩展配置的入口点，然后验证用户可以配置一组扩展，并且这些文件会获得 Lua 语言支持。
