[Feature request] Add additional files via link into py.cafe

[maxschulz-COL]

Would it be possible to link to files via the plug-in, something like

{.python pycafe-link additional_files="https://github.com/mckinsey/vizro/blob/main/vizro-core/docs/assets/user_guides/data/iris.csv <other file path>"}

and they are automatically added to py.cafe?

This would enable more comprehensive docs examples involving CSS or a data file.

I presume grabbing code from another code tabs is too difficult right?

Updating this issue to add a link to the workaround we've done for now in the Vizro docs.

We have created a specific PyCafe account https://py.cafe/vizro-official which hosts 13 projects which require additional files to enable the Python code under demonstration to work when the project launches.

Take a look at the code in the purple admonition in this section for an example: https://vizro.readthedocs.io/en/stable/pages/user-guides/custom-components/#trigger-actions-with-a-custom-component

Rather than use the mkdocs plugin, because this project needs a pair of visual assets, we have created a project and linked at the bottom of the code to this project so that it is fully set up with the assets folder in situ. I formatted the link and used the same text to mimic that of the plugin.

Ideally we'd not need to do this because there would be a way to resolve the assets (or CSS) or [requirements.txt](https://py.cafe/vizro-official/vizro-iris-analysis) through additional instructions to the plugin.
