Fedora compilation instructions are incorrect

[FranciscoSilveira]

I tried the setup on a completely new system with Fedora 40, following the instructions, and I noticed some of them were wrong:

• Besides rocblas-devel and hipblas-devel you also need the rocm-hip-devel package, otherwise you'll get an error about 2 missing header files: hip/hip_fp16.h and hip/hip_runtime.h
• I did not have to link anything on /opt, all libraries were found with no issue, but it was looking for the amdgpu-arch which in Fedora is amdgpu-arch-17. I fixed this by symlinking /usr/bin/amdgpu-arch-17 to ~/.local/bin/amdgpu-arch

That last issue only happens if you don't specify the GPU architecture, which you have to like the guide specifies, otherwise you'll get a runtime error after loading the model into memory. I can open a PR for the README, but I'd like someone else to confirm this if possible.
