Fixing metrics (#14719)

**Description**
Several *arr applications support metrics. However, they were missing a
`targetSelector` that points the `ServiceMonitor` resource to the
correct `service` which is named `metrics`.

It also fixes a bug for uptime-kuma where the metrics configuration
points to the port named `metrics` which does not exist. The metrics for
uptime-kuma are exposed via the regular service on the `main` port.

⚒️ Fixes  #14468

**⚙️ Type of change**

- [ ] ⚙️ Feature/App addition
- [X] 🪛 Bugfix
- [ ] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] 🔃 Refactor of current code

**🧪 How Has This Been Tested?**
Manually applied the changes to the `ServiceMonitor` resources using
`kubectl patch` to see if the metrics started working. They did, so
these changes will ensure the `ServiceMonitor` resources will be
deployed with the right `matchLabels` and `port` values.
