Pin Docker version to 27.5.1

The latest Docker version 28.0.1 seems to no longer start properly on
GHA https://github.com/restatedev/restate/actions/runs/13562737120/job/37909085871#step:6:47
and https://github.com/restatedev/restate/actions/runs/13549192188/job/37868461603#step:6:47

This commit fixes the version to the last known working Docker version
27.5.1. We should revert this change once Docker releases a newer version
that is working again.
