In the system color PR I updated the prettier config to match what we use on zed.dev. I didn't want to format all of styles as it would add a lot of unrelated line changes to that PR.
Doing that format now.
Now you simply specify a text, an action and a style and GPUI will
take of rendering it properly. This is simpler compared to always
providing a custom element and should make tooltip more consistent
across the UI.
