Add riscv and ppc builds in the releases

- Operating System Linux
- Core Version: 2.53
- Client Version:

## Expected behavior

Download builds for those linux targets

## Actual behavior

its not there

### Steps to reproduce the problem

1. enter releases page
2. read the files listed

### Screenshots

### Logs

it will be great if we can also distribuite a build for HaikuOS at some point because afaik it's not possible to build it there yet

Start at the releases page and compare the listed Linux artifacts with the requested RISC-V and PPC targets. Trace the release build configuration that produces those artifacts; done means downloadable builds for both targets are published, with HaikuOS treated as a separate future request.
