When bulk editing several posts the message is wrong

[markoheijnen]

When you bulk editing posts you always get the message that the posts are edited:

see: sprintf( _n( '%s post updated.', '%s posts updated.', $updated ), number_format_i18n( $updated ) );

Should it be getting the name and singular there or add it to the post updated messages array?

Looks like the rest of the messages there were moved to use 'Item' and 'Items' back in [12728], It seems to make sense that we should update it to use the same 'Item' phrasing here.

We can't simply inject the Singular name from the CPT array registration here unfortunately, as with translations, it can become rather messy (Which is exactly why the post editor page has a filtered array of items).
