Tooltip triggers are inaccessible to keyboard users

Using the [Accessibility page](https://2023.stateofhtml.com/en-US/features/accessibility/) from the latest (2023) survey, the tooltip triggers are inaccessible to keyboard users.

Because they contain click handlers, NVDA users in particular will hear "clickable" for every node using this construct. This happens even though they cannot trigger the tool-tips and the node itself may have no text to convey. On this page, an NVDA user has to hear "clickable" at least 105 times. Use this XPath to confirm the count:

```
//div[contains(@class,"Tooltip__Trigger")]
```

I encourage you to move away from JS event handlers and lean on `:focus` style triggers by default, adding in `:hover` when the `:focus` has been built.
