Update ci-build.yml - add codecov upload token

[srajiang]

Adds repository upload token to git action

Summary

Public repositories shouldn't technically require a token to upload to codecov. However, we are seeing failing this PR for example here. Per recommendation here, adding an explicit token to see whether that makes the situation better.

LGTM and I'm hopeful that the token will fix this, nice find! 🔍

We might also want to add the CODECOV_TOKEN secret to the Dependabot section of secrets too – not sure if this token is shared between the normal Actions secrets 🤔

@zimeg - Thanks, yep added to the Dependabot section as well. Merging and fingies crossed.
