Fix/mermaid support doc

[simonprovost]

Urban Pipeline is quite a substantial component of Urban Mapper. It therefore deserves attention. We first fix an issue with mermaid and material for mkdocs (plugin related). Then we made sure that the viz. is substantial enough to understand the capabilities of the urban pipeline.

Cheers :)

Since there are only two possibilities — either including a visualiser or not — using '(0..1)' may be misleading, as it implies a continuous range or multiple values between 0 and 1. Consider replacing it with something more explicit like 'Visualiser (0, 1)' to indicate a binary choice.

Enhance the PR description. It doesn't have to be extensive—just a sentence summarizing the changes.
