Add package installation guidelines to README.md

[luigimorel]

Hey,
I'd like to add the package's installation guidelines to the README file.
This would make it easier for the users to install the package in their projects by simply copying and pasting the command to their terminals.

Could this issue be assigned to me?

Let me know what you think of the above.

Hey there, do you mean something like go get github.com/golang-jwt/jwt/v4@latest or the command line tool?

hey @mfridman,
yes, that's what i mean.

is it vague? would love to get your opinion.

If it helps users, even those new to Go, then it seems reasonable. Typically there would be an "Install" or "Installation" section in the readme with a command such as:

go get github.com/golang-jwt/jwt/v4@latest

And maybe a reference to the Go tooling installation: https://go.dev/doc/install#testing

Great, will send a PR.
