Create (extra) 3.5.0 release with consistent download URL

[haampie]

ref ROCm/ROCclr#18

Currently the download URL for the releases is inconsistent:

https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime/archive/roc-3.5.0.tar.gz
https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime/archive/rocm-3.7.0.tar.gz

Could you maybe create another Github release for 3.5.0 which reads rocm-3.5.0? This makes it easier for packages managers to automatically detect new releases/versions and have an educated guess about their download url.
