Ignore international column on ApplicationQualifications

[inulty-dfe]

Context

The field international in the applications_qualifications table is no longer used. it is false for all qualifications after 2022. We do not update it when someone creates a non uk qualification. Instead we use the presence of non_uk_qualification_type (string) as a proxy for the qualification being from another country.

Having an unused field like this is noisy and causes confusion when collecting and analysing data.

Tech debt: Remove international field

[inulty-dfe]

I don't think this has been correctly identified as a field we can remove without a significant investigation into how it's used.

Closing this PR and put the ticket into Triage.
