A lot of times when we talk to engineering managers, they ask about some way they can easily make their whole team use Watermelon's VS Code extension.

If we could have some button that says "Add Watermelon to this repository", which adds Watermelon to the list of recommended extensions of such, it would be awesome.

There's a .vscode/extensions.json file on every repo. Add Watermelon to such and we're done.
