Code Insights: Refactor capture group live preview
Created by: vovakulikov
Based on https://github.com/sourcegraph/sourcegraph/pull/33609 Closes part of https://github.com/sourcegraph/sourcegraph/issues/32944
Background
This PR migrates capture group insights live preview from old live preview abstractions (god like components) to low-level abstractions for building insight card and live preview insight in particular. It's very similar that we've done in this PR https://github.com/sourcegraph/sourcegraph/pull/33609 for search based and for lang insights live previews before. To achieve this this PR introduces a new abstraction components over InsightCard components for building live preview cards UI (on creation UI pages and the landing page) - see LivePreviewCard components.
This PR also extracts the live preview fetching logic into separate re-usable hook and therefore simplifies live preview logic for all live previews besides capture group.
Test plan
- Make sure that all preview charts have the right layout
- Make sure that all preview charts send minimum number of request during falling out form fields (that debouncing works properly)
- Make sure that dynamic insight example on the in product landing page works properly
