Allow rendering of Mermaid charts in notebooks and when importing markdown files, to support flowcharts/diagrams/schematics written in Mermaid.
### Pre-submit Checks - [x] I have [searched Warp feature requests](https://github.com/warpdotdev/warp/issues?q=is%3Aissue+label%3AFEATURE) and there are no duplicates - [x] I have [searched Warp docs](https://docs.warp.dev) and my feature is not there ### Describe the solution you'd like? We are slowly building a developer KB for a product we are working on via the Import feature in Warp Drive. Many of our existing KB articles have flowcharts/diagrams/schematics written in Mermaid, but Warp doesn't properly parse the mermaid script, it displays the raw script itself and not a diagram. It would be extremely useful if Warp supported Mermaid Charts displaying correctly as they are a huge help for our support engineers. ### Is your feature request related to a problem?
