Subject: [PATCH 1/2] ci(fresh-install): add findutils to arch/tumbleweed
 distro legs

quick_install.sh (fetched from xlings main) locates the extracted
xlings dir with `find`. On opensuse/tumbleweed:latest, which ships
without findutils, the install died with:

    bash: line 148: find: command not found
    exit code 127

before mcpp ever ran. The arch leg lacked an explicit findutils too
and only passed because the base image bundles it.

List findutils explicitly on both legs (matching fedora/debian/ubuntu)
and add a matrix note so the hard `find` dependency isn't dropped again.

Failing run: https://github.com/mcpp-community/mcpp/actions/runs/27796803895

Subject: [PATCH 2/2] ci(fresh-install): drop redundant GITHUB_PATH append in
 container leg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The findutils fix unmasked a second, tumbleweed-only failure at the
start of "Configure mcpp":

    OCI runtime exec failed: exec: "sh": executable file not found in $PATH
    exit code 127

opensuse/tumbleweed's image declares no PATH in its config. Appending a
single dir to $GITHUB_PATH makes the runner exec every later step's
`sh` with only that dir on PATH, so /usr/bin/sh becomes unfindable. The
setup/install steps passed only because they ran before the append.

Every container-matrix step already does
`export PATH="$HOME/.xlings/subos/current/bin:$PATH"` in its own
script, so the GITHUB_PATH append was redundant — and the sole cause of
the corruption. Drop it. (The bare linux-fresh leg keeps its
GITHUB_PATH: its later steps call mcpp directly without re-exporting.)
