Change deployment strategy from RollingUpdate (default) to Recreate
to resolve volume attachment conflict. The forgejo-data PVC uses
ReadWriteOnce access mode, which only allows attachment to one pod
at a time. RollingUpdate tries to start new pod before terminating
old pod, causing multi-attach error.
With Recreate strategy, old pod terminates first, volume detaches,
then new pod starts and successfully attaches the volume.
Resolves: DEV-380
