Error parsing security reports because of the schema version

A customer (internal link) is seeing the following error parsing security reports:

[Schema] Version 15.2.1 for report type dependency_scanning is unsupported, supported versions for this report type are:
15.0.0, 15.0.1, 15.0.2, 15.0.4, 15.0.5, 15.0.6, 15.0.7, 15.1.0, 15.1.1, 15.1.2, 15.1.3, 15.1.4. GitLab will attempt to validate this
report against the earliest supported versions of this report type, to show all the errors but will not ingest the report

It started happening for them some time between Jan 10th and 13th, 2025, and they're running GitLab 17.2.9-ee.

A similar problem was recognized in this issue. It should be resolved in the major image, but that didn't change the behavior the customer's seeing.
