rattler_conda_types::Version::to_string() does not preserve case

[0xbe7a]

When uploading packages with rattler-build, we use different fields from parsed IndexJson to upload packages to anaconda.org. If we attempt upload a package with version 1.2.3_Beta1, it will fail because the original version case is lost after parsing and version.to_string() will return 1.2.3_beta1. Subsequently a release 1.2.3_beta1 is created but anaconda.org rejects the package upload as the versions from the IndexJson and the release are not the same. While it is true that 1.2.3_Beta1 == 1.2.3_beta1 when comparing versions, rattler should return the version with the original version when calling .to_string().

The following unit-test should pass:

#[test]
fn preserve_case() {
    let v = "1.2.3-Beta1";
    let version = Version::from_str(v).unwrap();
    assert_eq!(version.to_string(), v);
}

We have VersionWithSource for that use case. Does that help?

Yeah, missed it. Works perfectly for this use-case
