Consider adding `kid` jwt header by default

[adamJLev]

So it looks like PyJWKClient relies on this param to work at all, why not make it the default to include kid in the JWT headers?
If the field is empty or null, the JWK client will never match the key.

I realize kid is an optional field, but its useful and it would make sense to me to include it, as otherwise the client that comes with the library doesn't even work with JWT tokens signed by this library - which seems inconsistent.

More info on kid aka `key id" field: https://datatracker.ietf.org/doc/html/rfc7517#section-4.5
