HedgeDoc 1.9.x bundles Mermaid version 9.1.7, which is old enough that current Mermaid syntax will fail to render inside HedgeDoc notes. Add a pointer to Mermaid 9.1.7 docs, so users of the current stable HedgeDoc know what's actually supported. https://github.com/mermaid-js/mermaid/blob/v9.1.7/docs/n00b-gettingStarted.md Signed-off-by: Jordi Mallach <jordi@igalia.com>
