README.md code-snippet Helptext for 'mailkeys_skip' ist incorrect

Problem/Motivation

In the README.md (code-snippet) is written:

// A line-delimited list of message keys to be rerouted. Either module machine
// name or specific mail key can be used for that. Use case: we need to reroute
// only a few specific mail keys (specified mail keys will be rerouted, all
// other emails will NOT be rerouted).
$config['reroute_email.settings']['mailkeys'] = 'somemodule, mymodule_mykey';

// A line-delimited list of message keys to be rerouted. Either module machine
// name or specific mail key can be used for that. Use case: we need to reroute
// all outgoing emails except a few mail keys (specified mail keys will NOT be
// rerouted, all other emails will be rerouted).
$config['reroute_email.settings']['mailkeys_skip'] = 'somemodule, mymodule_key';

The 1st paragraph is correct. The 2nd is about mailkeys_skip and it should start with:

> // A line-delimited list of message keys NOT to be rerouted.
