Implement hub for adding new templates

[TRMSC]

Actually the code of index.html has to be changed when a new template was added in the template directory.

• Add a json file in the template directory with a structure for enrolling a new template (name, description, author)
• Implement areas in the index.html for showing the content of the json file
• Add a function in the script.js for integrating the templates with names, descriptions and authors
• Get template contents by using an universal and relative link Revise reference to templates #9
• Create a documentation for adding templates

Thank you @fdagner for mentioning that point in #9! It is included in the roadmap now! 😊👍

Implement a two way solution for getting the template path correctly when using github pages or a server e.g. for forking with 44f0a41 and bc03b93.

Good work. It works on a server in VSCode.

Can we add your authorname in the templates.json e.g. in form of your github handle or full name @fdagner? 😊

(We can create the descriptions later because I think it is better to try different forms for that when the functions are implemented - maybe keywords, a short sentence or something else...)

You can add Florian Dagner

Perfect, thank you! 🥳 I also wrote a description for the Bubbles Template to complete the content but you can make revisions of course! 👌
