Describe the bug

Some tempo dashboards still use the "graph" visualization.

To Reproduce
Steps to reproduce the behavior:
Provision e.g. https://github.com/grafana/tempo/blob/a7511b698ae072ec3b2c5a80142e52c6e7be1998/operations/tempo-mixin-compiled/dashboards/tempo-tenants.json into a current Grafana. Observe warnings about AngularJS being deprecated.

Expected behavior
All panels are using visualizations which are non-deprecated, e.g. "timeseries".

Environment:

• Infrastructure: Kubernetes
• Deployment tool: terraform + helm (but it's irrelevant)
