Describe the bug

context

I am using jupyter-book to build tutorials such as this one:

https://oggm.org/training-lahore/day_4/04_glacier_water_resources.html#interactive-glacier-map

Recently (after updating jupter-book, sphinx-book theme, etc, the builds new raise this warning:

/home/mowglie/disk/Dropbox/HomeDocs/git/oggm-edu-notebooks/oggm-edu/glacier_water_resources_projections_pre16.ipynb:200002: WARNING: skipping unknown output mime type: application/vnd.holoviews_load.v0+json [mystnb.unknown_mime_type]

/home/mowglie/disk/Dropbox/HomeDocs/git/oggm-edu-notebooks/oggm-edu/glacier_water_resources_projections_pre16.ipynb:200002: WARNING: skipping unknown output mime type: application/vnd.holoviews_exec.v0+json [mystnb.unknown_mime_type]
/home/mowglie/disk/Dropbox/HomeDocs/git/oggm-edu-notebooks/oggm-edu/glacier_water_resources_projections_pre16.ipynb:580002: WARNING: skipping unknown output mime type: application/vnd.holoviews_exec.v0+json [mystnb.unknown_mime_type]

The page however displays correctly

expectation
This did not happen in earlier versions.

problem
This is a problem because the warnings are verbose and do not seem to indicate a real issue in web rendering

Reproduce the bug

Create a book with an interactive plot from bokeh, for example:

# hvplot is a plotting library relying on bokeh
# you'll need to install it alongside with pandas for this cell to work
import hvplot.pandas

# pandas is a very useful data analysis library
import pandas as pd

# This makes the plot
ts = pd.Series(index=x, data=y)
ts.hvplot().opts(title='An interactive plot', width=500)

Then build the book

You can hide these warnings if you need to, using this Sphinx configuration option: suppress_warnings = ["mystnb.unknown_mime_type"]. That can be set in _config.yml:

sphinx:
  recursive_update: true
  config:
    suppress_warnings = ["mystnb.unknown_mime_type"]
