Today label should be removed from accessibility grid table

The date header of the accessibility data grid shows the label "Today", instead of it being blank or called "Date".

1. Enable accessibility.
2. Navigate to Analytics Hub.
3. Open one of the indicators.
4. Scroll down on the page to the grid table. Notice the misleading label "Today" showing on the table, even though there is no real-time set-up.
