test(sweeps): fix code coverage to track src not tests

[kelu-wandb]

Code coverage was previously broken and only tracking coverage on tests themselves not the code under test.

• Before: tests dir https://app.codecov.io/gh/wandb/sweeps/pull/125/tree
• After: src/sweeps dir https://app.codecov.io/gh/wandb/sweeps/pull/126/tree

Only running code coverage on the python 3.10 tests, not 3.11 and 3.12.

Outside of this PR, also looked up CODECOV_TOKEN from https://app.codecov.io/gh/wandb/sweeps/config/general and added it to https://app.circleci.com/settings/project/github/wandb/sweeps/environment-variables as well as configured comment report.
