Pull request overview

This pull request reorganizes the logging documentation by moving all logging-related docs and snippets into a dedicated "logging" subfolder under docs/core/extensions/. The PR also modernizes the high-performance logging documentation to prioritize source-generated logging (using LoggerMessageAttribute) over the legacy LoggerMessage.Define approach.

Changes:

• Moved 9 logging documentation files to docs/core/extensions/logging/ subfolder with appropriate redirections
• Rewrote high-performance-logging.md to focus on source-generated logging as the primary approach, relegating LoggerMessage.Define to a legacy section
• Updated 30+ files with corrected path references to moved logging documentation

• According to Markdown Writing Style Guidelines (Guideline 1000002), avoid using "you will" in instructions. Change "you will learn" to present tense "you learn" or use imperative mood. The sentence should read "In this article, you learn about console log formatters."
