Fix a row in the job patterns table

[dougkoch]

In the raw Markdown, the row for the "Queue with Variable Pod Count" pattern has one more column than the other rows. The extra empty cell (in column 2) shifts the checkmarks one column to the right of where they should be. Reading through the example of how this job pattern works, it's clear that columns 2, 3, and 5 are the ones that should be checked.
