v0.135.0

## 🎉 Dashboards: the new experience is live

[Dashboards](https://signoz.io/docs/dashboards/overview/) now use a Perses-compatible schema and the new [v2 APIs](https://signoz.io/docs/dashboards/dashboards-v2-api/)  delivered alongside a set of highly requested experience and performance enhancements. 

Read the [v0.135.0 upgrade guide](https://signoz.io/docs/operate/migration/upgrade-0-135/) before upgrading, dashboards are converted in place and the v1 dashboard APIs are retired.
