[CI] Use ovs-vsctl to ensure bridges

The upstream openvswitch collection has been deprecated and was not
included in newer Ansible (like Ansible 11). Since jobs switched
to Ansible jobs relying on these tasks are failing.

This patch switches to use ovs bridge command same
as add-port in next tasks.

Also add the role to irrelevant-files as single node
jobs need not run on multi node role changes.

Also fixed pre-commit error by switching to
fix-byte-order-marker.
