Artifacts unavailable in RPM format

[angusscott]

The script contains references to rpm for installation on Fedora, Rocky, RHEL etc. However neither Bor nor Heimdall release artifacts in the rpm format, as you can see at both of these links

https://github.com/maticnetwork/heimdall/releases/tag/v1.0.2
https://github.com/maticnetwork/bor/releases/tag/v1.0.6

Preferably, rpm support would be added to both the release pipelines for these projects
