Check for updates about hoard

Can you help me with the implementation of a function for updating hoard cli?

[Hyde46]

Sure!
Similar to how trove files are imported by url here. You can create another function to request the latest version of hoard.
In bash, it could work like this:

  curl --silent "https://api.github.com/repos/$1/releases/latest" | # Get latest release from GitHub api
    grep '"tag_name":' |                                            # Get tag line
    sed -E 's/.*"([^"]+)".*/\1/'                                    # Pluck JSON value

translate that to a reqwest call and some string operations to find out the latest version tag of the project, then compare to the version of the currently running process

const VERSION: &str = env!("CARGO_PKG_VERSION");

and inform the user if there is a newer version available.
If there's no network connection, or any other issue with requesting the tag, fail silently.

Pluck the new function in somewhere around here

So I don't have to fetch the latest version package and replace the existing one

[Hyde46]

Initially no.
Only informing the user about a new version would satisfy this feature.
In an additional step, we could think about how self-update could work

Implemented with #238
