This patch extends the duration for the longhorn-share alert, that was
hotfixed with the hotfix-7183 cronjob. Since the cronjob runs every 5
minutes, this patch extends the alert to 10 minutes to catch possible
hotfix failures.

Currently when the share-pod simply doesn't exist the hotfix doesn'T
trigger correctly and therefore never patches the error state.

Instead it errors out with the following message:
```
Error from server (NotFound): pods "share-manager-pvc-36c42839-3899-41fe-bfe3-a6308982d671" not found
```
