Changes to production Docker image

[VKTB]

Description

This PR fixes the issue reported in #76 so any custom images created using the prod Docker image from Harbor as the base image while being in a different working directory would not result in any issues now. It also addresses #77 so the default logging in the prod Docker image will be to the console.

Testing instructions

Add a set of instructions describing how the reviewer should test the code

• Review code
• Check Actions build
• Start a container using prod Docker image from this PR and ensure that it logs to the console only by default
• Start a container using the Dockerfile below and ensure that the fix for ModuleNotFoundError when using the prod Docker image as the base image and changing the working directory #76 is working and app logging can be changed to log to file

# Use the LDAP JWT Authentication image on Harbor as the base image
FROM harbor.stfc.ac.uk/ldap-jwt-authentication/auth-api:pr-78

WORKDIR /ldap-jwt-auth-run

USER root

RUN set -eux; \
    \
    mkdir logs; \
    \
    # Change ownership of logs/ - app will need to write log files to it \
    chown -R ldap-jwt-auth:ldap-jwt-auth logs/;

WORKDIR /ldap-jwt-auth-run/ldap_jwt_auth

# Copy the custom logging.ini file
COPY --chown=ldap-jwt-auth:ldap-jwt-auth logging.ini ./logging.ini

USER ldap-jwt-auth
