Add functionality to control ordinal type for headers within nb outline view

[Saunak626]

Below is a screenshot of what I mean. I'd like it to show only the headers of the notebook, not each and every single markdown block. Is there a similar way to changing this, like in JupyterLab, where you can toggle different outline options?

Numbering
Enumerate headers of the jupyther notebook

1. Only markdown with headers is generated into the outline
2. Ability to customize the ordinal type and automatically sort the generation in multi-level headers.

For example, the markdown header generation plugin Number Headings in obsidian


Thank you!

The request to only have headers is covered by #200060

Adding a note from a duplicate issue regarding the ability to remove the icon from outline entries in order to reduce visual noise (specifically the markdown icon, but could in theory be applied to the rest via altering the renderTemplate)
