Upgrade nginx, DependencyTrack and trivy

[stephdl]

Brief description

Upgrade the nginx Docker image used in DependencyTrack. Two versions are under consideration: the latest stable nginx:1.28.0 or the current nginx:1.29.0. See PR #23 for the Trivy update and PR #15 for previous nginx updates.

upgrade dependencytrack frontend and apiserver

• Keeps the deployment secure and up-to-date.
• Ensures compatibility and stability by considering both the latest and stable releases.

Proposed solution

• Evaluate the impact and stability of both nginx:1.28.0 and nginx:1.29.0 in the DependencyTrack context.
• Prefer to upgrade to nginx:1.28.0 if it is more stable, otherwise adopt nginx:1.29.0.
• Merge the relevant PR after assessment and testing.

Alternative solutions

• Upgrade directly to nginx:1.29.0 without further assessment, but monitor for potential issues.
• Retain the current nginx version if neither upgrade is suitable.

Additional context

• Regular updates to base images are critical for security and reliability, but care is needed with major/minor changes.
