fix: ban version v3.1.7 of DOMPurify

[DOMPurify v3.1.7][1] forbids the use of `<foreignElement>` for HTML
inside of an `<svg>` element, which breaks many mermaid diagrams.

It is likely that v3.1.8 will add a new option that will allow us to
re-enable this behaviour, but v3.1.7 definitely does not work.
