fix(ci): Correct SRPM architecture to prevent binary RPM overwrite

Source RPMs were incorrectly being registered with x86_64 architecture
instead of 'src', causing them to overwrite the binary RPM in the package
registry. This resulted in the 16MB binary being replaced by the 847KB
source package. SRPMs now correctly use 'src' architecture.
