fix: helm - alloy.mounts.extra adds unnecessary newline

[splichy]

PR Description

It's just cosmetics but alloy.mounts.extra is using range for some reason, I have no idea why, but it just adds an unnecessary newline after dash:

# values.yaml
alloy:
    mounts:
      extra:
        - name: tmpalloy
          mountPath: /tmp/alloy

# charts/alloy/templates/controllers/daemonset.yaml
          volumeMounts:
            - name: config
              mountPath: /etc/alloy
            - name: varlog
              mountPath: /var/log
              readOnly: true
            - name: dockercontainers
              mountPath: /var/lib/docker/containers
              readOnly: true
            -
              mountPath: /tmp/alloy
              name: tmpalloy

Change from range to with

          volumeMounts:
            - name: config
              mountPath: /etc/alloy
            - name: varlog
              mountPath: /var/log
              readOnly: true
            - name: dockercontainers
              mountPath: /var/lib/docker/containers
              readOnly: true
            - mountPath: /tmp/alloy
              name: tmpalloy
