Parses invalid versions with leading 0 in numeric prerelease identifiers

[Nemo157]

repro (playground):

fn main() {
    println!("{:#?}", semver::Version::parse("1.0.0-alpha.01"));
}

prints:

Ok(
    Version {
        major: 1,
        minor: 0,
        patch: 0,
        pre: [
            AlphaNumeric(
                "alpha",
            ),
            AlphaNumeric(
                "01",
            ),
        ],
        build: [],
    },
)

when it should be some form of error.

See semver/semver#563 for clarification that this should be an error case, and cc downstream bug rust-lang/crates.io#2463.

This is fixed in 1.0.0.

fn main() {
    println!("{}", semver::Version::parse("1.0.0-alpha.01").unwrap_err());
}
