[CI:DOCS] Treadmill script: add --reset option
Buildah got vendored into podman last week, and the script went kablooie because of ever-so-slight conflicts between what was in the treadmill PR (#13808) and what ultimately got merged (#14127) which was obviously better (hey, I tried). After a buildah vendor, there really isn't any point to keeping the treadmill commits - we're much better off just restarting with two fresh empty placeholder commits. Do so. Also, mild cleanup.
