Replicate schema files from EE into Core

What does this MR do and why?

Part of #347093 (closed)

With gitlab-org/security-products/security-report-schemas!97 (merged), we ensure that the security-report-schemas are copied to both EE and Core locations.

This MR retroactively copies the existing schema files from EE to Core since the changes to the deploy script above will only take care of new versions.

There is a follow-up to consolidate the files in a single location: #351405.
