Changing the status code of an exception isn't possible

[lgv5]

Summary

Remove the paragraph stating that the status code of a reply->exception can be changed. Amend the "Also" at the beginning of the next paragraph.

Motivation

Bashed my head too many times trying to understand why $self->reply->exception->rendered(400) was returning an HTTP 500 status code. It isn't possible.

16:56 < Lucas_> question: https://docs.mojolicious.org/Mojolicious/Guides/Rendering#Rendering-exception-and-not_found-pages says that I can change the status code of an 
    exception with ->rendered, but that isn't working. Tried both Mojolicious 9.37 and 9.39
16:56 < Lucas_> there is also an issue, https://github.com/mojolicious/mojo/issues/1014 , which says it won't be supported
16:57 < Lucas_> so, which one is it?
17:26 < kraih> The docs are wrong

This is a sentence fragment; better would be just saying "You can change..." without "also".

Indeed, that reads way better.
