Licenses are displayed as None

I just installed cargo-show v0.5.9, and no matter what crate I view with it, the license is always displayed as None. For example, despite clap's crates.io page saying it's licensed under MIT or Apache-2.0, cargo show clap gives:

---
id: clap
name: clap

documentation: None

Interesting!

• https://crates.io/crates/clap is showing metadata for the most recent version in the sidebar:

• cargo show is using the crate key from API endpoint https://crates.io/api/v1/crates/clap response, but it doesn't include the license key (the unofficial API might've changed?)

• clap's license changes from null to MIT to MIT or Apache-2.0 in the API response the versions field (cargo show --json clap | jq -c '.versions[] | {num: .num, license: .license}')

I'll try to find some time to update cargo show to use metadata from the most recent version to match crates.io behavior. IMO that would surprise people the least.
