This pull request makes several improvements to the documentation in src/getting-started/06-testing-debugging.md, focusing on clarity, consistency, and accuracy. The changes primarily standardize terminology (e.g., "Source" vs. "source"), improve grammar and punctuation, and clarify instructions for using the Event Delivery tool.

Documentation consistency and clarity:

• Standardized the capitalization of "source" throughout the document for consistency and updated related references in descriptions of the Debugger and Event Delivery tool. [1] [2]
• Improved grammar and punctuation in explanations and instructions, such as clarifying how to select a time period and updating bullet point formatting for key metrics and error details. [1] [2]
• Enhanced the description of the Error Details view by consolidating bullet points, adding missing information about the "Response from Destination," and refining links to related documentation.

Formatting and style:

• Removed unnecessary blank lines and adjusted section headings for better readability.
• Updated phrasing for better readability, such as rewording when Event Delivery is most useful and how to pause the Debugger stream. [1] [2]
