Fix: Codecov in workflow

[n-thumann]

What

This PR fixes Codecov in our workflow.

Why

To have Codecov working again.
For whatever reason we already have secrets.CODECOV_TOKEN present, but we're not using it.

References

This kind of error has been first introduced in #668, but can't really tell why. Also, the error got shadowed by another one, because in the CI runs prior to that one it also failed due to a different error.

Only a remark: Do we need a conventional commit for this change? Asking because with this it will end up as a changelog entry for Troubadix on the next release here:

https://github.com/greenbone/troubadix/releases

while this is completely not about Troubadix but just some internal repo maintenance.

AFAIK from other projects it's not uncommon to have also changes that are not directly related the actual code in the changelog 🤔 I'd don't mind keeping it there, but I leave that up to discussion

IMHO any changes not directly related to the software shipped with a repository shouldn't end up in the changelog of that repository. This is something i personally really dislike in these other projects:

As a user of the software i have no interest in anything other then actual changes to the software, a changelog should purely contain only changes to the software itself and shouldn't include anything development related like e.g. "Codecov" as i simply not using that.
