fix: Ensure Tooltips work with anchors that have an as prop

[frankieyan]

Short description

This fixes an issue where if you used a tooltip anchor with an as prop, it gets doubly applied, creates a nested element, and loses the anchor's children in the process 😬

Example:

<Tooltip content="Some helpful info">
  <Box as={Link} to="/help">Hover me for info</Box>
</Tooltip>

...would result in something like:

<a href="/help">
  <a href="/help"> />
<a>

You could test this in storybook by undoing the fix, then using <Box as={Button}> as an anchor.
