This pull request includes several changes to the JsonToHTML utility class to improve the formatting of JSON data when rendered as HTML. The most important changes include modifying the indentation level, updating the title formatting method, and enhancing the title formatting logic.

• Changed the initial indentation level from 0 to 2 in the renderJsonToHTML method.
• Replaced the capitalizeFirstLetter method with formatTitle to improve title formatting by splitting camel case words and capitalizing the first letter of the resulting title.
• Updated the renderObject method to use the new formatTitle method instead of capitalizeFirstLetter.
