Subject: [PATCH] Add Renovate rules for UBI8 images on `release-1.x` branches

MintMaker/Renovate reads config only from the default branch (`main`),
which only had rules for `ubi9` images. The `release-1.1` and
`release-1.2` branches use `ubi8/ubi-minimal` and `ubi8/go-toolset`
in their Containerfiles, so Renovate silently skipped them.

Add `matchBaseBranches`-scoped rules for both UBI8 images to enable
base image digest updates and Go toolchain version bumps on release
branches.
