chore: use jwt-library instead of separate packages

[joostdebruijn]

When installing this package, Composer will show the following warnings:

Package web-token/jwt-key-mgmt is abandoned, you should avoid using it. Use web-token/jwt-library instead.
Package web-token/jwt-signature is abandoned, you should avoid using it. Use web-token/jwt-library instead.
Package web-token/jwt-signature-algorithm-ecdsa is abandoned, you should avoid using it. Use web-token/jwt-library instead.
Package web-token/jwt-util-ecc is abandoned, you should avoid using it. Use web-token/jwt-library instead.

This PR replaces the abandoned packages by the web-token/jwt-library package.

You can use the rc though but I'd recommend not to
