This pull request improves the clarity and readability of the docs/non-functional-requirements/reliability.md documentation by refining grammar, punctuation, and sentence structure throughout, as well as updating references to resilience engineering resources. The changes help make the recommendations easier to understand and more actionable for readers.

Documentation improvements:

• Refined grammar, punctuation, and sentence structure across multiple sections to improve readability and clarity, including changes such as adjusting comma placement, updating phrasing for parallelism, and clarifying examples.
• Updated the circuit breaker section to reference Microsoft’s Resilient Coding Patterns for concrete implementations of resilience patterns, alongside the Polly library.

Reliability practices and testing:

• Improved the explanation of maintenance exercises and chaos testing, including corrections to terminology (e.g., “service meshes” instead of “services meshes”), and clarified instructions for scenario fabrication and playbook updates.
• Enhanced the list and descriptions of chaos testing tools, and corrected references to hypothesis-driven chaos tests and related documentation.
• Clarified recommendations for post-mortem documentation and linked it to Agile retrospectives, correcting spelling and phrasing for better guidance.
