Code Insights: Support color for compute powered insight
Created by: vovakulikov
Closes https://github.com/sourcegraph/sourcegraph/issues/38832 Fixes https://github.com/sourcegraph/sourcegraph/issues/39917
Background
Considering a given timeframe for Sourcegraph 4.0, we disable multi-series support for compute-powered insight. This PR
- hides add a new series button in the creation UI
- adds colour picker to series creation form
- adjust the insight card layout for the compute-powered insight. Now it doesn't render legend block (see related comment https://github.com/sourcegraph/sourcegraph/pull/39805#issuecomment-1205879211)
Test plan
- Go to the compute insight creation UI
- Create compute insight (make sure that you can't have more than one series)
- See that this insight was created correctly, and you can see it on the dashboard page.
