Workspace level .vscode for jellyfin-plugin-sso

Per jellyfin-plugin-sso#17, for now we'll avoid committing any IDE specific artifacts.

I personally don't know that I agree with this, since I think vscode is lightweight & ubiquitous enough to be worth supporting, and giving development workflows is useful to reducing friction in onboarding, but I respect the owner's wishes.

This repo literally just provides some vscode workflows, settings and extension recommendations for the project.

Usage

1. clone/fork https://github.com/9p4/jellyfin-plugin-sso
2. cd jellyfin-plugin-sso
3. clone this git clone https://github.com/matthewstrasiotto/jellyfin-plugin-sso-vscode .vscode

Feel free to fork this for your own changes or whatever you wanna do with it really.
