Comment:
This should probably print a similar message to steam if there's an  README.voidlinux, I don't think looking for a `README.voidlinux` in output of `xbps-query -f` (or `/usr/share/doc/$pkgname` for that matter) is the first thing users would do if something doesn't work or am I wrong?
```
steam-1.0.0.74_2: post-install message:
========================================================================
Consult /usr/share/doc/steam/README.voidlinux for further installation
instructions and troubleshooting information.
========================================================================
steam-1.0.0.74_2: installed successfully.
```
At some point `java-runtime` and `java-environment` should probably be bumped to JDK 17 since it is the latest LTS release after all, so then installing an older JDK may only be necessary for older MC versions.
