PR Summary

• Upgrade of nginx image
  The Dockerfile, which provides the instructions to create the Docker image for the nginx server, has been updated. We have now moved to a more recent version of nginx (1.25.3) replacing the older 1.25.1. This move ensures that we benefit from the latest improvements and security fixes in nginx.

• Setting the Time Zone
  The 'TZ' environment variable in the Dockerfile has been adjusted to 'Asia/Tokyo'. This means that all timestamps and system time within the running Docker container will adhere to the Asian/Tokyo time zone. It helps align the system time with local operational hours if your work or servers are primarily based in this time zone.
