Run CI/CD pipelines for external repositories - form should be hidden by default

Summary

When creating project via "run ci/cd pipelines for external repositories" form should be hidden by default exactly in a way it is hidden when we create project via "import project"

Steps to reproduce

  1. Open New project
  2. Select run ci/cd pipelines
  3. Observe form being seen without clicking "Repo by URL" button
  4. Observe "Repo by URL" button not toggling form

Implementation plan

This issue will require GitLab license to fix. You will get one at https://about.gitlab.com/free-trial/

We should be able to fix this without any changes in our JS code - we have toggle behavior implemented in app/assets/javascripts/behaviors/toggler_behavior.js. Basically I think we're missing hide class on form itself to make it hidden by default and js-toggle-container class on page (similar to page "import project"
