Add tooltip to the license explanation popover disclosure

[sarayourfriend]

Problem

In https://github.com/WordPress/openverse-frontend/pull/850 we implemented a new license explanation popover; however, we left out the tooltip that is meant to show on the disclosure due to the reasons outlined in this comment https://github.com/WordPress/openverse-frontend/pull/850#issuecomment-1047815002

Description

We need to add a VTooltip component that implements the accessible behaviors for this kind of component. Once that is added, wrap the license explanation popover disclosure with it to show the tooltip on hover/focus. Please refer to the WAI-ARIA spec for the tooltip role.

Implementation

• [ ] 🙋 I would be interested in implementing this feature.

Here are the Figma links to:

• Tooltip component
• Help component. Tooltip is visible in hover state

@obulat Do you have a sense of whether this would be a good first issue or help wanted? I'm not familiar enough with the frontend anymore to make a good judgement of that.
