[SPARK-57546][K8S] Use `eclipse-temurin` to use `Ubuntu 26.04` and `Python
3.14` by default
Like `Apache Spark Docker` repository, this PR aims to use
`eclipse-temurin` to use `Ubuntu 26.04` and `Python 3.14` by default for Apache
Spark 4.3.0.
https://github.com/apache/spark-docker/blob/75f9e755807c67794776276d8f5e3e2ceedfa82b/4.1.2/scala2.13-java17-ubuntu/Dockerfile#L17
Apache Spark 4.3.0 dropped Python 3.10.
- #55914
However, `azul/zulu-openjdk` only supports `Ubuntu 22.04` which doesn't
support Python 3.11 officially. It only have `Python 3.11.0rc1`.
```
$ docker run -it --rm azul/zulu-openjdk:25 bash
root3c66cb6be8be:/# cat /etc/os-release | grep VERSION_ID
VERSION_ID="22.04"
root3c66cb6be8be:/# apt-get update
root3c66cb6be8be:/# apt-get install -y python3.11
root3c66cb6be8be:/# python3.11 --version
Python 3.11.0rc1
```
Note that previously we support this new combination by the following.
```
$ bin/docker-image-tool.sh -b java_image_name=eclipse-temurin build
```
A user can switch back manually in the same way.
```
$ bin/docker-image-tool.sh -b java_image_name=azul/zulu-openjdk build
```
Although Apache Spark behavior is not changed because it's orthogonal to
the underlying JDK, OS and Python versions, yes, the underlying OS becomes
`Ubuntu 26.04` and Python becomes `3.14` and Java vendor becomes `Eclipse
Temurin`. This is inevitable due to the lack of Python 3.11 support of `Zulu
JDK`.
**AFTER**
```
$ docker run -it --rm eclipse-temurin:25-jre bash
rootde506cc01b8a:/# cat /etc/os-release | grep VERSION_ID
VERSION_ID="26.04"
rootde506cc01b8a:/# apt-get update
rootde506cc01b8a:/# apt-get install -y python3
rootde506cc01b8a:/# python3 --version
Python 3.14.4
```
Pass the CIs.
