Show row and column counts in the table list on pages like "Discover"

**Is your feature request related to a problem? Please describe.**
When looking through available databases/tables in the [Discover Databases](https://www.dolthub.com/discover) page, it is often unclear what the scope/scale of the databases are.

**Describe the solution you'd like**
In the middle column of the Discover page's results, I want the number of rows and number of columns for each table in each database shown right beside that table's name.

**Describe alternatives you've considered**
* Hovering over each table could also show this info, but seems less friendly.
* It would be even better if hovering over the column count number (to be added) showed the names of all the columns. I understand that such a feature might be pretty resource-intensive though, and might go unused.

**Additional context**
This came up when I searched for "stocks", and saw tons of results. It was difficult to see what the scale of such stock examples was though, and what each table meant.
