Update readme

[abhi18av]

This pull request updates the README.md to improve clarity and consistency in the documentation for NEAT's configuration parameters and example usage. The most important changes are a reformatting of the parameter descriptions into a markdown table and the use of explicit YAML code blocks for configuration examples.

Documentation improvements:

• Reformatted the list of configuration parameters into a markdown table for better readability and organization in README.md.

Example usage consistency:

• Updated all configuration file examples to use explicit yml code blocks rather than generic code blocks, making it clearer that these are YAML files. [1] [2] [3] [4] [5] [6]
