Missing version 0.4.6

Latest version on crates.io is [0.4.6](https://crates.io/crates/leetcode-cli). Latest version here is [0.4.5](https://github.com/clearloop/leetcode-cli/releases).

I maintain the Arch [AUR package](https://aur.archlinux.org/pkgbase/leetcode-cli/) and got flagged for an out of date version but I rely on the github release notification.
