Simplify and sync .pylintrc config for cleaner linting (Fixes #1456)

[sreesushmavad]

I updated the .pylintrc file to make our linting output more useful and less noisy.

• Disabled common docstring warnings (C0114, C0115, C0116) and R0903 since they were cluttering the output.
• Set max-line-length=100 for readability.
• Ignored the tests folder during linting.
• Added pydantic to the extension whitelist.

Resolved merge conflicts so that local changes and the upstream config are now in sync.

Result: Linting is now more consistent across environments, and the pylint score became more meaningful (improved from ~8.0 → ~9.26 ).
