Exclude renew and upgrade URLs from E2E broken link checks to prevent unintended order creation

[hanna-meda]

The E2E test introduced in PR #329 that validates WP Rocket settings pages for broken links is currently following wp-rocket.me/renew/ and wp-rocket.me/upgrade/ URLs.

These URLs trigger order creation on the production website when accessed, which has resulted in hundreds of unintended pending orders being generated by the E2E test account (mai+autoe2e@wp-media.me).

Expected:
E2E broken link checks should not follow or validate URLs that:

• Contain /renew/
• Contain /upgrade/
  The test should ignore any URL that triggers transactional side effects.
