Update runner admin page to make description field larger

What does this MR do?

This MR changes the size of the 'descition' and 'version' columns in the runner admin page. Its goal is to make the 'description' column larger to make longer descriptions easier to read. Currently even short descriptions are cut off and require a mouse hover to fully read. To compensate for the extra space the 'version' column is made smaller.

I chose a new column size of 20 for the description field and a size of 10 for the version field. These used to be 15 for both.

What are the relevant issue numbers?
