fix(parameters): resolve freeze issue when updating auth model concurrently

[hamzamahmood]

What

• This PR improves the thread safety and reliability of parameter handling by:
• Replacing the List used for collecting parameters with ConcurrentBag to ensure safe concurrent access.
• Updating unit tests to account for the unordered nature of ConcurrentBag by comparing parameter sets in an order-independent way.
• Fixing an incorrect README.md file path in the .csproj file to ensure the file is properly included in the build/package output.

Why

• Thread Safety: The original use of List was not safe in concurrent scenarios, which could lead to race conditions or inconsistent parameter states. Using ConcurrentBag eliminates this issue.
• Test Stability: Since ConcurrentBag does not guarantee order, the unit tests were updated to validate parameter content regardless of sequence, ensuring deterministic and reliable test results.
• Project Cleanliness: The incorrect file path for README.md in the project file has been corrected to maintain project integrity and consistency.
