title: Cypress Migration Assistent appears on all branches, instead of the test-runner
body: <p>I have migrated one of my branches to Cypress 10.6
  There are other branches, which shall further run on a lower Cypress version.
  When I now run <code>npx cypress open</code> on one of my un-migrated branches, then the Migration Assistent appears. Instead of the old Cypress test-runner.</p>
  <p><strong>How can I get rid of the Migration-Assistent and back to the normal test-runner?</strong></p>
  <p>I don't want to migrate those branches, yet.</p>
