Update Mermaid to v8.4.5
This fixes a problem rendering multiple graphs on the same page (https://github.com/mermaid-js/mermaid/pull/1190).
Full list of changes: https://github.com/mermaid-js/mermaid/releases
Mermaid v8.4.4 also fixes an HTML escaping issue (https://github.com/mermaid-js/mermaid/issues/903). Since HTML labels are disabled, the HTML content can remain as-is, and we just need to ensure the XSS doesn't actually get run.
Closes #195802 (closed)
