Allow Codecov upload to fail in build workflow

[rpatel-figure]

Context

Codecov continues to log the following error in the CI workflow

['verbose'] The error stack is: Error: Error uploading to [https://codecov.io:](https://codecov.io/) Error: There was an error fetching the storage URL during POST: 404 - {'detail': ErrorDetail(string='Could not find a repository, try using repo upload token', code='not_found')}
    at main (/snapshot/repo/dist/src/index.js)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

I had allowed the step to cause a failure if the upload failed in hopes that it would eventually resolve itself, but that hasn't been the case and it's simply inconvenient to continue letting builds have a failing status for a problem out of our control

Changes

• Disable Codecov upload failures from propagating to the workflow
