[PATCH 2/5] gitlab-ci: ignore failures to disable realtime monitoring

In-Reply-To: <20251002-pks-gitlab-ci-windows-improvements-v1-0-6a8b6b45d728@pks.im>

We have recently introduced a change to disable realtime monitoring for Windows job in GitLab CI. This change led (and still leads) to a quite significant speedup.

But there's a catch: seemingly, some of the runners we use already have realtime monitoring disabled. On such a machine, trying to disable the feature again leads to an error that causes the whole job to fail.

Safeguard against such failures by explicitly ignoring them.
