Subject: [PATCH] Fix: customMermaidURL can be used in site and frontmatter
 (#518)

Change param name to lower case,
since all site-level configuration keys are stored as lower case.
According to official hugo documentation:
https://gohugo.io/functions/isset/

This allows loading custom mermaid.js using the config option,
as specified in https://learn.netlify.app/en/basics/configuration/
