Create a new weekly workflow to run all QIT tests against the WC Nightly build

[cesarcosta99]

Description

To ensure compatibility with the latest WooCommerce developments, we should introduce a weekly GitHub workflow that runs all QIT tests against the WC Nightly build. This will help catch potential regressions early and ensure smooth integration with upcoming WooCommerce versions.

Acceptance criteria

• The workflow should trigger automatically once per week.
• It should execute all managed QIT tests and QIT custom E2E tests – check the Managed Tests section.
• It should run against the latest WooCommerce Nightly build.
• Any failures should be logged and reported for review.

References

You can check the QIT and the QIT E2E tests workflows for reference.

Tagging @diegocurbelo to avoid duplicate efforts as you were supposed to work on this too. Please align with @cesarcosta99 to make sure multiple people are not implementing the same thing.
