Updated codecov action to v5 in build_and_test.yml

[rickecon]

This PR updates the codecov-action in build_and_test.yml to v5. This fixes an issue with the ubuntu CI GitHub Actions in which the CodeCov action would give the following error:

Error: Codecov: Uploader shasum does not match -- uploader hash: 4a9a4d50df1cb796229e27f8dcc292bf5538779cd906851b37eb361202a43dce  codecov, public hash: 8930c4bb30254a42f3d8c340706b1be340885e20c0df5160a24efa2e030e662b  codecov"
