feat(lms): backport support for openedx-commerce plugin to Nuez

[jignaciopm]

Description

This PR backports two key changes from openedx/edx-platform into the Nutmeg-based edunext Nimbus SaaS distribution. The goal is to allow our SaaS clients to use the new WordPress plugin openedx-commerce, which only supports Quince or later.

Currently, some clients use the legacy plugin edunext-openedx-integrator, which has not been maintained since 2020. This backport enables a migration path to the community-supported plugin without requiring a full upgrade to Quince.

Included changes:

• Backport of PR: openedx/edx-platform#33006
• Backport of PR: openedx/edx-platform#33059

Supporting information

• This PR is part of the plan to officially deprecate support for the edunext-openedx-integrator plugin.
• Once deployed, clients will be notified via Lotus to switch to the openedx-commerce plugin.
• The old plugin will then be removed from the WordPress plugin repository.
