Riverpod extension for VSCode

[Trung15010802]

I am someone who knows nothing about TypeScript and programming extensions for VSCode. I worked on this for 2 days, so this repository is not perfect.

Please create a Pull Request if you can help me improve it!

Note that Riverpod already provides such refactor, using riverpod-lint

Yeah. My extension isn't as good as riverpod_lint. But sometimes riverpod_lint doesn't work (I have to activate it again), and I don't want to import custom_lint and riverpod_lint just to use the right context menu in all of my projects
