Bump cross-spawn from 7.0.3 to 7.0.6

We'd love to show you visual changes, but your branch doesn't have a Chromatic build yet. Here's what you need to do:

1. Checkout dependabot/npm_and_yarn/cross-spawn-7.0.6 if you haven't already.

   git checkout dependabot/npm_and_yarn/cross-spawn-7.0.6

   Don't forget to install or update dependencies after switching branches.
2. Create a build for dependabot/npm_and_yarn/cross-spawn-7.0.6
