Merchant dispute e2e tests fail when running on WooCommerce 7.7

[Jinksi]

Describe the bug

Merchant dispute e2e tests fail when running WooCommerce 7.7. This caused the GH workflow E2E tests - All to fail before tests were skipped (#7486) in order to explicitly mark the test as broken while a solution is in progress (this issue).

Skipped tests:

• merchant-disputes-save-draft-challenge.spec.js
• merchant-disputes-submit-winning.spec.js
• merchant-disputes-submit-losing.spec.js

These tests fail on WC 7.7 because the "Respond now" button is not rendered on the edit order screen for WC < 7.9. This is because the disputed order notice requires the hook woocommerce_admin_order_data_after_payment_info that was added in WC 7.9 (changelog entry).

Note

Keep in mind that we need to keep tests for the flow Order Screen Dispute Notice → Dispute Details, so we should ensure this flow continues to be included in e2e tests for WC v7.9+.

To Reproduce

1. Un-skip the e2e tests mentioned above.
2. Run e2e tests with WC 7.7
   1. This can be done in a local environment or by,
   2. Running the GH action "E2E tests - All" against a branch that has un-skipped the tests listed above.
