This is needed after the recent switch to cirrus runners in the task in commit c8c9c1e61759f689615a304254fed33cda7f895e.
Otherwise, the CI will fail:
0 node1 stderr Error: Unable to bind to 127.0.0.1:12321 on this computer. Bitcoin Core is probably already running.
(https://github.com/bitcoin/bitcoin/actions/runs/22398358349/job/64837827234?pr=31723#step:9:2605)
Also, include a random second commit, so that the CI task is run in this pull.

11000, right?
Changing CIRRUS_CACHE_HOST to be below 11000 would be a smaller diff in this file… wait - https://github.com/cirruslabs/cirrus-ci-docs/issues/310 I guess we’ve been down that lane before.
