FR: Custom codeblock to display bibliography in file

[lguenth]

Hey! Yesterday, some people on Discord were discussing different options to display a dynamically updated bibliography as part of the opened document, similar to how the Word integration for Zotero works. I thought it might be a great addition to your plugin to include a similar funcitonality, perhaps as a custom codeblock, similar to how Dataview and Breadcrumbs display and update results. This would likely only be usable for drafts and notes since it would break in an export with Pandoc but, at least for me, it would be really helpful if I could close all sidebars, go into focus mode and still see the bibliography.

for the code block format, I'd suggest two options:

1. normal code block:

```refs
```

2. directly use pandoc's placeholder for references

::: {#refs}

This would be a great feature!
