Feature Request: Support for Mermaid.js v11+ (without markdown-it-mermaid)

[Thyme-Kirihara]

Hi 👋 Thank you for your great plugin — it's been very helpful for my Neovim workflow!

I'd like to propose support for Mermaid v11+ in markdown-preview.nvim.
Since markdown-it-mermaid doesn't support modern Mermaid (v11+), I've created a working patch that:

• Converts ```mermaid blocks to <div class="mermaid">
• Adds mermaid.min.js script loading (from CDN or _static)
• Initializes Mermaid via mermaid.initialize({ startOnLoad: true })
• Keeps markdown-it-mermaid untouched (optional alternative)

Would you be open to accepting a PR that adds this as an optional feature, disabled by default?

Thanks for considering!

it is very sad to say this, but this project stopped being updated since 2023.
so if you want some new features the only thing will work is pulling other patched repo or put some dirt on your own hand..

Could you open a PR or share the patch @Thyme-Kirihara ? Thanks

there are many PRs updating the mermaid.min.js file.

you can fork this repository and patch mermaid source file.
then simple replace the plugin source repository with your own fork repo.
i'm also using this plugin like this to get latest mermaid support.

check this out link to get mermaid version you want.

I think you did something more like linking to the original source. I already changed mermaid.min.js in place, but the actual solution for me was creating a base node js project and embedding mermaid.min.js and https://www.npmjs.com/package/@mermaid-js/layout-elk to solve my problems.
Thanks for replying anyways.
