Summary

This pull request updates the .NET SDK telemetry documentation to improve clarity, privacy guidance, and formatting. The most important changes include a new section on avoiding inadvertent disclosure of sensitive information, a more readable and organized list of collected telemetry data by SDK version, and improved formatting of environment variable and agent tables.

• Move Privacy and disclosure guidance to be earlier in the article
• Replaced the previous data collection table with a version-organized, bulleted list, making it easier to see which telemetry data is collected in each SDK version.
• Added a link to the Microsoft Privacy Statement for more information about privacy and personal data collection.
• Updated environment variable and agent tables to use code formatting for variable names, improving readability and consistency.

Fixes #49866
