New review comment by JamiKettunen on void-packages repository

Comment:
Why? `virtual?java-runtime` will accept any package that provides `java-runtime` virtual dependency, this includes both `openjdk17-jre` and the [current distro-wide default of `openjdk8-jre`](https://github.com/void-linux/void-packages/blob/4475c34/etc/defaults.virtual#L25).

If you install `openjdk17-jre` you should be able to remove `openjdk8-jre`, or why not keep both. You could also install `openjdk17-jre` before `PolyMC` and then `openjdk8-jre` won't be pulled in.
