please upgrade mermaid to support gitgraph

[heartacker]

https://github.com/mermaid-js/mermaid/releases/tag/9.0.0

and the newest version is 9.1.1

I see mermaid is added as a devDependency.

• Why is that?
• Does this extension depend on the mermaid as a peerDependency?
• If I need to upgrade the underlying version of mermaid. How do I do that?

@detj because mermaid is built to the extension bundle at compile time.

I just figured out how to update mermaid bundled with the extension (as a temporary workaround):

• In VSCode, locate extensions folder via command: Extensions: Open Extensions Folder
• Open terminal and cd to said folder, then cd to this extension folder (bierner.markdown-mermaid-1.13.2)
• Install all dependencies, including devDependencies: npm install
• Generate new page.bundle.js file (the extension bundle) with command: npm run build-mermaid
• That's it. Restart the extension or VSCode to see new mermaid gitGraph syntax now render properly.

We don't need to run other build commands.

At that point, why not just submit a pr :)

@mjbvz will do. Like I said, it was temporary. But currently I need that gitGraph feature urgently, and I know I cannot rush open source author. :)
