Remove role attribute from recharts-wrapper (#4386)

<!--- Provide a general summary of your changes in the Title above -->

<!--- Describe your changes in detail -->

Before this PR, there was a `role` attribute on both the
`.recharts-wrapper` parent DIV, as well as the SVG element. This is
unnecessary, since the SVG element is enough. That extra role also
caused problems, as I outlined in
#4384

This PR removes the `role` attribute from the `.recharts-wrapper`
element. The SVG element still retains its role.
