Codecov actions require tokens for v4

You'll also need a token to use v4: codecov/feedback#112

Token is already present in https://github.com/pangeo-data/climpred/settings/secrets/actions. Followed https://docs.codecov.com/docs/quick-start

Odd, it doesn't seem to be accessible within the CI builds: https://github.com/pangeo-data/climpred/actions/runs/8344829496/job/22838239963#step:10:34

Let’s see whether that’s it: #854

[aaronspring]

Seems to have worked. Didn’t it? https://github.com/pangeo-data/climpred/actions/runs/8364695563/job/22900659283?pr=854 @Zeitsperre

@aaronspring Looks like it did! Closing this issue.
