Mermaid Diagram Themeing

re: 1f1d455

Do you know of a good way to theme mermaid for both themes? We've tried a few things
but due to things like litestar-org/litestar#2053 we ended up with litestar-org/litestar#1687.

I'd like a better way if you have an idea :D

You'd better use raw mermaid, in this way, you can use mermaid_init_js setting:

mermaid_init_js = """
mermaid.initialize({theme:"forest"});
"""

You can find all the options here: https://mermaid.js.org/config/schema-docs/config.html
