remove `.coveragerc` file

[cadenmyers13]

closes #57. With tests at top level, we no longer need to omit any files as pytest automatically detects files in tests. https://github.com/Billingegroup/cookiecutter/pull/177#discussion_r1826404794

This isn't passing after I made a second push, similar to the other PR here https://github.com/diffpy/diffpy.fourigui/pull/55

Edit: Looks like this is an active issue faced by others. I've created an issue for this. Solution is being worked out here but will look into this: https://github.com/codecov/codecov-action/issues/1580

@sbillinge Yeah... there's a github thread here discussing it: https://github.com/codecov/codecov-action/issues/1580

Thanks @cadenmyers13

Looks like the codecov problem is resolved too!
