org.freedesktop.Platform needs update as 23.08 is end-of-life

[MartijnRas]

For a while now flatpak gives following:

Info: runtime org.freedesktop.Platform branch 23.08 is end-of-life, with reason: org.freedesktop.Platform 23.08 is no longer receiving fixes and security updates. Please update to a supported runtime version. Info: applications using this runtime: com.github.babluboy.bookworm

When can we expect an updated version?
