Mermaid JS included too many times

[astrojuanlu]

I was noticing general slowness in our docs and lots of waiting time on unpkg, so I opened the source and noticed this in our docs:

<script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
        <script >mermaid.initialize({startOnLoad:true});</script>
        <script src="[https://unpkg.com/mermaid/dist/mermaid.min.js](view-source:https://unpkg.com/mermaid/dist/mermaid.min.js)"></script>
..

And I had to cut it because...
