fix: bump Trivy to v0.69.2 following supply chain incident

[Aloui-Ikram]

What this PR does

Bumps TRIVYVERSION from v0.69.1 to v0.69.2 in the Makefile.

Why

On March 1st 2026, the aquasecurity/trivy repository was targeted by
a supply chain attack. A bot exploited a misconfigured GitHub Actions
workflow to obtain a write-scoped token, which was used to permanently
delete all GitHub Releases between v0.27.0 and v0.69.1.

As a result, Harbor's current TRIVY_DOWNLOAD_URL returns HTTP 404,
breaking any build that uses TRIVYFLAG=true.

Aqua Security responded quickly they patched the vulnerable workflow,
recovered the repository, and published v0.69.2 as an emergency release
on the same day.
