error: failed to retrieve index of crate versions from registry

Caused by:
azure_data_cosmos_native not found in registry (crates.io). For workarounds check https://github.com/obi1kenobi/cargo-semver-checks#does-the-crate-im-checking-have-to-be-published-on-cratesio
```

Solution: Do not semver check packages that have `publish=false`
