Feature request: support Grafana 8 time series panel

[rickychandra]

With the time series type visualization panel being out of beta in Grafana 8 now (replacing the old graph type visualization panel), is there already a plan to support it in Grafonnet soon?
I know it's possible to migrate to the time series from graph with only a single button click, but we're using Grafonnet to version the whole dashboard and every code changes will override the migrated panels.

Thanks!

PS: I am willing to contribute if it's ok to do so.
