The Ubuntu specific wrappers "adduser" and "addgroup" have been removed with Ubuntu 24.04. Also, lets be more compatible with LSB this way.

It was left as "root" by accident, but should obviously be not.

Also delete some unused packages like gpg and dirmngr

- The entrypoint now defines two locations, which can be overridden by a user _without_ implicitely trying to execute these scripts.
- The entrypoint now _removes_ any files found at these locations to _always_ start with a clean slate. Otherwise stale files might be looped over and over again.
- A consequence of this: any kind of commands to be included must be provided via a script and cannot be provided by some initial file.
- The configuration scripts no longer leave temporary files dangling and avoid these files if possible. Instead, we are injecting statements into these files while checking for duplicates as a safety measure.

…application

Setting these env vars when reloading are highly application specific and shall not reside in the base image.

- Provide env vars for admin, linux user and domain master password.
- These are set to the publicly known values, good enough for development or demo purposes.
- For production purposes, these variables will be used to change passwords at run/boottime of the container.
- As of this commit, do _not_ leave any password lying around in files, which could be exploited.

A new init script allows to set passwords at boot time of the container. If the passwords are not changed, there will be warnings logged about the default in use.

Slightly modifying the startInForeground.sh script to avoid keeping password files or sensitive passwords around after starting the server.

Aligning configbaker and base image with same tool. wait4x has much more features to wait for different services.

As per https://docs.docker.com/reference/dockerfile/#automatic-platform-args-in-the-global-scope BuildKit / buildx will expose the target architecture. It requires adding an ARG in the Dockerfile to inject the data.

jattach binary is now available for ARM64 and AMD64, but requires special handling with download URLs and checksums.

Variable names related to user, password, and domain in Dockerfile and scripts have been modified for better clarity and consistency.

This includes changing the names of admin user and password, domain master password, and Linux password and user.

 Also includes a release note

This reverts commit 146c927.

We can't use 0.44 because of this error:

"Unable to inspect image [solr:]"
