refactor: Replace Reakit with Ariakit

[frankieyan]

Short description

This replaces Reakit with Ariakit, which powers our Menu, Tooltip, and Tabs components.

This includes a breaking change for Tabs, where if the selectedId prop is provided, it becomes a controlled component and will no longer switch tabs on its own. To retain the old behaviour, defaultSelectedId will need to be used instead.

Test plan

Each of the components should behave like the previously deployed version at https://doist.github.io/reactist/:

Menu

• You can tab in and out of each menu item
• With the "With sub-menu" example, a tooltip appears when you focus on the menu trigger
  • Pressing enter to select a menu item should place the focus back on the trigger, but not show the tooltip

Tooltip

• Hovering or focusing on the box shows its tooltip

Tabs

• Each demo's tabs show their corresponding content
• Note that this is different from the deployed docs: In the canvas tab, selecting a value for selectedId prevents tabs from being changed when they're clicked on. Instead, in the actions tab, you'll find the onSelectedIdChange callback being logged

PR Checklist
