The tools binaries only are published for one minor version per major version of RHEL. When the db tools team added rhel88 and rhel93 versions of the binaries, they stopped publishing rhel80 (amd64), rhel82 (arm64), and rhel90 versions.

Route the package tester to instead pull down the latest rhel version that matches the major rhel version of the package (ex. rhel80 package -> rhel88 tools)

This will be compatible because the tools binaries do not depend on any system libraries that are not guaranteed to be compatible across minor versions (per https://access.redhat.com/articles/rhel8-abi-compatibility#Guidelines):
