Please remove aria-haspopup="true" from tooltip markup

[carmacleod]

If an element has aria-haspopup="true", it means "this element pops up a menu".

But a "bx--tooltip__trigger" div doesn't pop up a menu, so this is misleading to screen reader users.
(i.e. they will hear "menu button" or something similar, and expect to arrow through menu items; and some screen readers even give a keyboard hint that the user can type down arrow to open the menu, which doesn't make sense here).

Please see the special note in the ARIA spec for aria-haspopup:

NOTE
A tooltip is not considered to be a popup in this context.

Here is the markup in the Carbon React Storybook for Tooltip:

<div class="bx--tooltip__trigger" role="button" tabindex="0" aria-haspopup="true" aria-labelledby="__carbon-tooltip-trigger_bmbcpfuzeiu" aria-expanded="false">
  <svg>(?)</svg>
</div>

Please completely delete aria-haspopup from this markup. This attribute is not needed here.
