Specify os and cpu for release name to avoid duplicates

actions/upload-artifact@4 made a breaking change to fail on duplicate
names. I think we are seeing Windows release errors as a result since
both x64_x86 and x64 are named 'releases'.

This change just tags the os and cpu onto the release dir name to
reflect the specific build.
