[Request] Define buttons in workspace settings

[ryandickerhoffgecko]

Instead of defining buttons in a script-buttons.json file, define the buttons in .vscode/settings.json.

.vscode is more likely to already be gitignored in a shared repo and is cleaner than adding a gitignore specifically for script-buttons.json.

Came here to ask the same thing... The code to find the file seems pretty straightforward so had a go at implementing it myself :)
