Allow For Private Mermaid Docs

[ss186222]

Is your feature request related to a problem? Please describe.
The current online hosted editor of mermaid.js allows anyone with the link to view and access the documents being worked on, which may not be desirable for some users who want to keep their documents private..

Describe the solution you'd like
I would like to request a feature that allows users to create private documents in the online hosted editor of mermaid.js. This feature would ensure that only authorized individuals can access and view the documents

Describe alternatives you've considered
Alternatives: One alternative solution could be to implement user authentication, where users need to sign in or provide credentials before accessing the documents. Another alternative could be to generate unique access codes or passwords for each document, allowing only those with the correct code or password to view the document.

Additional context
Additional context: It is important to address the privacy concerns of users by implementing a feature that allows them to create private documents in the mermaid.js online hosted editor. This would enhance the security and confidentiality of sensitive information while using the editor.
