Show dependency graph on package details page

vcpkg has the option to generate dependency graphs (in several formats) for packages.
It would be nice to add the graph to the package details page.

Example
```mermaid
flowchart TD; ableton --> ableton-link; ableton-link --> asio; ableton-link --> vcpkg-cmake; ableton-link --> vcpkg-cmake-config; asio --> vcpkg-cmake; asio --> vcpkg-cmake-config;
```
