Update nginx to stable and php8.4 for Webserver

[stephdl]

Brief description

Evaluate and upgrade the nginx Docker image for ns8-webserver, considering the recent proposal in PR #100 to move to nginx:1.29.0. However, nginx:1.28.0 might be a preferable option.

• Ensures the webserver runs with a secure and stable version of nginx.
• Maintains compatibility and minimizes risk by considering the most suitable version.

upgrade php8.4 to a minor upgrade

Proposed solution

• Assess the stability and compatibility of both nginx:1.28.0 and nginx:1.29.0 for ns8-webserver.
• Prefer the upgrade to nginx:1.28.0 if it is more stable or less disruptive.
• Merge the relevant PR after evaluation and testing.
• upgrade php8.4 to a minor upgrade

Alternative solutions

• Upgrade directly to nginx:1.29.0 as proposed, but monitor for any regressions.
• Remain on the currently used version if neither upgrade is suitable.

Additional context

• Dependency updates are crucial for security and stability, but caution is advised with major/minor version jumps.
