ipynb files displaying in book without formatting

[joemcglinchy]

Describe the bug

context When I commit changes with an ipynb, I want the output and formatting preserved. I have tried setting execute to off, auto, and force, but force is not ideal because i have credentials being used which are being loaded to run the notebook but I don't want to publish access to them in the repository.

expectation I expected the published version to have formatting like I see when running the notebook locally... bold font for keywords like for, lambda, etc.

bug But instead it is rendered as plain text (Raw NBConvert?)

this could be a rendering issue

**problem**
This is an issue mainly in aesthetics. 

### Reproduce the bug

1. go to https://hydrosat.github.io/fusion-hub-docs/examples/order-service-example.html
2. see the text rendered as plain text, not python formatted

### List your environment

i will add that a local build has the rendering of the text I'd expect in the html.

github-actions build:

i'd like to bump this and ask now, is there a good way to clean out the gh-pages branch?

I was told that it's an issue with ipython 8.7.0 but I haven't figured out why yet.

This is because of this bug:

• https://github.com/ipython/ipython/issues/13845

It has been fixed and merged, but not yet released. We can close this issue once it is released. In the meantime, I recommend pinning IPython to avoid the latest version.

[joemcglinchy]

I pinned ipython!=8.7.0 and we are back in business! thank you so much. I had it pinned to a 7.x version before, but the formatting is looking good again.

@choldgraf ipython 8.8.0 got released
