Bug description

This may apply to other views, but I've only tested and verified within the Week view, and using the Axe DevTools extension in Chrome.

Regardless of whether there are any all-day events or not rendered in the all-day content row, the following WCAG violation is thrown when running an Axe scan on the week view of react-big-calendar:

Ensure elements with an ARIA role that require child roles contain them

Element Location: .rbc-row-content

<div class="rbc-row-content" role="row"><div class="rbc-row"></div><div class="rbc-row"></div></div>

The axe DevTools links out to this page for more information.

Any of the Storybook examples that already exist can showcase this, (but here's a sandbox where the Week view is the default view for quicker testing.](https://codesandbox.io/p/sandbox/react-big-calendar-example-forked-gv9kvv)

Let me know if any other information is needed for my issue report. Thanks!
