JWT Authentication SecurityBundle configuration references 'anonymous' security

[wiese]

The JWT Authentication docs make use of the anonymous option for the main firewall config.

This was removed in the 5.1-dev branch and causes an error when used:

/srv/api # php bin/console

In AnonymousFactory.php line 52:                                                                                                                   
The authenticator manager no longer has "anonymous" security. Please remove this option under the "main" firewall.

There is an extensive reasoning in the linked commit. I think the bottom line is mentioning the option in the api-platform documentation configuration example can simply be removed for the same effect.
