[25u Communication] Invitation for new maintainer

[Robert Mckenna]

Hi folks,

I'm sending this mail to notify the community that the current maintainers intend to step down for the JDK 25 Updates repository. [1]

We would like to invite prospective new maintainers of the OpenJDK 25u repository to step forward prior to holding a call for votes.

    -Rob
