Saving page does not work

[Thorarin]

For me it's impossible to save the configured wiki page.

https://github.com/flaviojs/dokuwiki-plugin-stylingpages/blob/master/action.php#L70 seems to refer to AUTH_WRITE, which is undefined. I think what is intended is AUTH_EDIT?

I would make a PR to change it, but it's a bit confusing for me on how this ever worked? I went back in history on the Dokuwiki source, and even in 2017 (before this plugin was released), it was called AUTH_EDIT and not AUTH_WRITE.
