`commitlint` job keep failing due to `feat: Allow configuring additional volumes, and volume mounts`

Problem

It seems the merge commit of !304 (merged) generated the commit message feat: Allow configuring additional volumes, and volume mounts, which fails commitlint job, like https://gitlab.com/gitlab-org/cluster-integration/auto-deploy-image/-/jobs/3201213793

✖   subject must not be sentence-case, start-case, pascal-case, upper-case [subject-case]

Proposal

Run commitlint always

diff --git a/.gitlab/ci/test.gitlab-ci.yml b/.gitlab/ci/test.gitlab-ci.yml
index b68db96..b7826cf 100644
--- a/.gitlab/ci/test.gitlab-ci.yml

and, we need to amend the commit a6c24804 to be feat: allow configuring additional volumes, and volume mounts.
