Remove Cypress GetTable package

When running the build, we were getting a "Corrupted Download" message
when trying to install Cypress. I believe this is due to the `get-table`
package requiring an older version of Cypress as one of its
dependencies.

Here's how I came to that conclusion:
cypress-io/cypress#4595
