Allow backtick-based code spans?

[heyvito]

Hi there, folks! I noticed that on mermaid.live, trying to use a value like Some test with `code` does not work. It prints a strange Unsupported markdown: codespan instead.
However, using <code> tags works flawlessly!

Could we add an option to render texts between backticks as <code> tags? Thought of an option to be opt-in and possibly not affect anything people already have done/are doing.

Does it makes sense? I think it may be important to make clear that this is one of my first contact with Mermaid, so perhaps there's something else that can be done that I overlooked!
