GHSA-m4gq-x24j-jpmf: Mermaid allows prototype pollution in bundled version of DOMPurify

The following bundled files within the Mermaid NPM package contain a bundled version of DOMPurify that is vulnerable to https://github.com/cure53/DOMPurify/security/advisories/GHSA-mmhx-hmjr-r674, potentially resulting in an XSS attack.

This affects the built:

dist/mermaid.min.js
dist/mermaid.js
dist/mermaid.esm.mjs
dist/mermaid.esm.min.mjs

This will also affect users that use the above files via a CDN link, e.g. https://cdn.jsdelivr.net/npm/[email protected]/dist/mermaid.min.js

Users that use the default NPM export of mermaid, e.g. import mermaid from 'mermaid', or the dist/mermaid.core.mjs file, do not use this bundled version of DOMPurify, and can easily update using their package manager with something like npm audit fix.
