Update the link to the SSV Grafana Dashboard Documentation

[JHGrove3]

The website ssv.network has been updated as of October 2025.

SSV Release v2.1.0 has new Grafana dashboards which are described in the SSV documentation on the website, and has templates that can be installed.

The new website update has broken the old links to this documentation.

The Old Location was:
https://docs.ssv.network/operator-user-guides/operator-node/monitoring/dashboard-runbook#ssv-operational-dashboard

The New Location is:
https://docs.ssv.network/operators/operator-node/monitoring/dashboard-runbook/

Please update the Github release v2.1.0 description with the new link, to help people find it. That page can be found here:
https://github.com/ssvlabs/ssv/releases/tag/v2.1.0

While you are at it, it's worth making sure all those dashboards still work with the latest releases of SSV.
