Upgrade mermaid to 10.9.0 (Latex support)

[maikol-solis]

Describe the bug

The new latest mermaid 10.9.0 has Latex support. mermaid-cli is still in version 10.8.0.

Merging the PR #663 will do it.

Best.

Switch to 10.9.0 is blocked by broken regression suite.

Mermaid v10.9.0 greatly increases the size of the bundle, and that seems to be causing issues with tests.

I'm looking into a way of fixing it but my gut feeling is that it might be a bit of work, since we might need to dig into Puppeteer internals to support splitting up the bundle into multiple parts, without triggering CSP/CORs errors.

This comment puppeteer/puppeteer#1229 (comment) looks promising!

Unfortunately, I haven't really had the free time to look at for the past few weeks, since I've been ill, but I'll see if I can get a chance to look at in the next few days! Otherwise, help would be appreciated!
