Accessibility: Display stats tables on /about/stats/

[dufresnesteven]

This was broken out from: #4120

We should display the hidden data table associated with each pie chart on ​https://wordpress.org/about/stats/.
See original ticket for a more robust discussion.

The data table is currently rendering in the DOM but it is being hidden, most likely by the chart library.

Sorry, what is "the underline data"?

Replying to Otto42:

Sorry, what is "the underline data"?

The data that is used for each Pie Chart is also displayed in a hidden table below each Pie Chart.

The request, included in 4891, is to show that data table based on this assumption:

"That would help all users, thinking for example at users who would like to copy and paste the data for later reuse." - @afercia

I suspect the problem here is that the data tables are only accessible via assisted readers(?)

What if we made a 'click to expand' button so anyone could see the tables if they want?

Main theme: Stats page: Allow changing the displayed pie chart into a table.

Fixes #4891.

I'm not 100% happy with the styles, so if someone else has ideas / patches / etc, re-open please with those suggestions :)
