feat: Update container images to use OpenJDK 25 (#46386)
This PR is mostly based on 303446b465.
Additionally, I made few tweaks to documentation and introduce a doc variable for the recommended Java version so limit required changing when migrating the recommended JDK version.

* Closes: https://github.com/keycloak/keycloak/issues/45830

Keycloak Image

For more information, see the Running Keycloak in a container guide.

Build the image

It is possible to download the Keycloak distribution from GitHub:

docker build --build-arg KEYCLOAK_VERSION=<VERSION> -t <YOUR_TAG> .

It is possible to download the Keycloak distribution from a URL:

docker build --build-arg KEYCLOAK_DIST=http://<HOST>:<PORT>/keycloak-<VERSION>.tar.gz -t <YOUR_TAG> .

Alternatively, you need to build the local distribution first, then copy the distributions tar package in the container folder and point the build command to use the image:

cp $KEYCLOAK_SOURCE/quarkus/dist/target/keycloak-<VERSION>.tar.gz .
docker build --build-arg KEYCLOAK_DIST=keycloak-<VERSION>.tar.gz -t <YOUR_TAG> .
