Update mermaid module

[manuelver]

I have changed the script

<script src="//unpkg.com/mermaid/dist/mermaid.js"></script>
  <script src="//unpkg.com/docsify-mermaid@latest/dist/docsify-mermaid.js"></script>
  <script>mermaid.initialize({ startOnLoad: true });</script>
  <script>
    mermaid.initialize({
      startOnLoad: true,
      securityLevel: 'loose',
      logLevel: 1
    });
  </script>

to

  <script type="module">
    import mermaid from "https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs";
    mermaid.initialize({ startOnLoad: true });
    window.mermaid = mermaid;
  </script>
  <script src="//unpkg.com/docsify-mermaid@2.0.0/dist/docsify-mermaid.js"></script>

in all index.html. As I have seen in the documentation
