Sitemap plugin shall honor grav page header flag visible

[trial-n-error]

Hi,

the sitemap plugin lists also invisible pages. Pages with the header "visible: false" probably should not be listed. They might be ignored by sitemap plugin configuration though.

Fix seems rather simple.

Best regards, Mario

"Not visible" means the page is not in the navigation https://learn.getgrav.org/content/headers#visible. But still, that page should be listed in the sitemap, as part of the site.

To remove a page from the site and from the sitemap you need to set it as published: false
