Web [Charts]: Use wildcard `Popover` instead of `floating-ui`
Created by: vovakulikov
Context
Prior to this PR, we used the floating-ui
tooltip for the chart tooltip component. Since we have our own Popover
component as a part of the wildcard package this PR simply replaces the floating-ui
with our Popover.
Test plan
- Make sure that all demos for the
/charts/line-chart
look good and don't have any problem with the tooltip
