feat: codeblock dot language (#6783)

* feat(CodeBlock): support dot language in code block

- render DOT using @viz-js/viz
- highlight DOT using @viz-js/lang-dot (CodeEditor only)
- extract a special view map, update file structure
- extract and reuse the PreviewError component across special views
- update dependencies, fix peer dependencies

* chore: prepare for merge
