Typos in get_items_per_page docblock for $option filter

[bobbingwide]

The docblock in WP_List_Item::get_items_per_page() for the $options filter hook contains two minor typos:

1. 'netework' which should be 'network'.
2. 'edit_$post_type}' missing the '_per_page' suffix.

I also noticed a couple of other tiny opportunities to improve it.

1. Remove 'may' from 'Possible values may include'
2. Add 'edit_post_per_page' and 'edit_page_per_page' before the generic 'edit_${post_type}_per_page.

I also notice that some of the parameters to protected functions are missing, but the @return is documented. I haven't addressed that in the first patch.
