Integrate Codecov to Display Test Coverage Badge

[niveditashankaranarayanan]

As a Developer, I need to integrate Codecov into the repository So that I can monitor test coverage and display a Codecov badge in the README.md file.

Details and Assumptions

• Codecov will be used to display test coverage in the repository.
• A Codecov token needs to be added to the GitHub repository secrets.
• CI/CD workflows will upload test coverage reports to Codecov.

• The Codecov badge will be added to the README.md file for visibility.

  Acceptance Criteria

Given Codecov is integrated into the repository,
When CI/CD workflows run,
Then test coverage reports are successfully uploaded to Codecov.

Given Codecov generates a badge URL,
When the badge is added to the README.md file,
Then it displays the test coverage percentage dynamically.
