Avoid failing YouTube CTL tests when network is slow

[kzar]

The YouTube Click to Load integration tests check a bunch of things, including that interacting with the YouTube Iframe API works correctly. Unfortunately, these tests fail sometimes when run inside a GitHub action since the test runner is too slow to load (or even request) the Iframe API script. When the script has failed to be requested in time, let's mark the test as pending (aka skipped) instead of declaring a failure.

Automated tests:

• Unit tests
• Integration tests

Reviewer Checklist:

• Ensure the PR solves the problem
• Review every line of code
• Ensure the PR does no harm by testing the changes thoroughly
• Get help if you're uncomfortable with any of the above!
• Determine if there are any quick wins that improve the implementation

PR Author Checklist:

• Get advice or leverage existing code
• Agree on technical approach with reviewer (if the changes are nuanced)
• Ensure that there is a testing strategy (and documented non-automated tests)
• Ensure there is a documented monitoring strategy (if necessary)
• Consider systems implications

Seems fine to me, it's better than disabling entirely.

Thanks for looking into this, I was going to spend some time on it next so you saved me :)
