added open jdk jre 25

[stokpop]

Added a reference to Java JRE 25 (based on changes in Java 21 Support issue #1035).

Solves #1121

However, creating a buildpack locally results in:

Unable to resolve version '25.+' for platform 'bionic'

Seems there is no Java 25 in https://download.run.pivotal.io/openjdk/jammy/x86_64/index.yml / https://java-buildpack.cloudfoundry.org/openjdk/jammy/x86_64/index.yml or https://download.run.pivotal.io/openjdk/bionic/x86_64/index.yml / https://java-buildpack.cloudfoundry.org/openjdk/bionic/x86_64/index.yml.

Is there a dependency on the availability on java 25 packages in those locations?
