Added Codecov Workflow

[UmairK5669]

Description:
Added a Codecov workflow that will allow pytest to perform any tests and upload the coverage to codecov using the pytest-cov dependency that has been added to pyproject.toml. This workflow will run on code that is pushed to the main branch as well as PRs that intend to merge into main.

Related Issues:
#12

Outstanding Sub-Issues:
This workflow simply uploads the test coverage to Codecov and doesn't check to see if it meets the threshold.

Tips for the Reviewer:
As there are no tests that Ria has presently, I would highly recommend adding dummy tests to test the workflow. After adding dummy tests run poetry run pytest to first ensure the tests are being ran, then push the code to this branch and the workflow will run automatically.

Checklist:
Please be sure to check all boxes honestly. This is to ensure a smooth development process, and to reduce the
likelihood of needing to make additional changes later on.

Should these dependencies be moved to the tool.poetry.group.test.dependencies?

Looks good overall, I think let's remove the dummy tests so they don't reach the main branch.

Note: We will need to squash the commits at merge time.

It looks like test_dummy.py is already in main, should we be removing it?

Yeah, I think they should, they don't really serve a purpose and were only for testing this workflow.
