Add code formatting and linting workflow

[rishipradeep-think41]

This pull request introduces a new GitHub Action workflow to automatically enforce code style and consistency across the repository.

• What was changed:

  • A new workflow file has been added at .github/workflows/lint.yml.
  • This workflow is triggered on every pull request that targets the main branch.
  • It runs isort --check . and black --check . to validate that the code adheres to the project's formatting standards as defined in pyproject.toml.

• Purpose:

  • The goal is to automate the process of checking for code style, ensuring all contributions are consistently formatted.
  • This will help improve code quality and readability, and reduce the need for manual formatting reviews.

• Dependencies:

  • To support this new workflow, isort and black have been added as development dependencies to requirements.txt.

This won't work for the dev branch yet, as we need to merge dev with main and then reset it. We will also need to run the linting process for the main branch once before this is merged, just to make sure.
