📚 A mistake in the limiter middleware source code comment

[qracer]

There is the config.go file in the limiter package. The file contains definition of config for limiter middleware. It has a field Max which sets maximum amount of requests. According to the comment beside it implies number of connections during Duration seconds, but Duration field is deprecated and Expiration field to be used instead. The comment is also confusing because the doc page about the limiter middleware does not have any mention for the Duration field at all except for the comment itself.
