chore(ci): bump comment in .gitlab-ci.yml to verify post-verification runner allocation

Pipelines on the GitLab mirror have been instant-failing with 0 jobs and
no started_at since the project was created — classic "shared runners
not allocated to unverified free-tier accounts" pattern. The account is
now identity-verified; this trivial comment bump exists solely to fire a
fresh pipeline that confirms runners now pick up the build-backend and
build-frontend jobs.

If the resulting pipeline produces real jobs that build the multi-arch
images and push them to registry.gitlab.com/bigbodycobain/shadowbroker/{backend,frontend},
the GitLab install path is at full parity with the GitHub one.
