[FIX] developer/tutorials: Button example without deprecated attrs

Using attrs to make a button invisible is deprecated since 17.0 but the button example hyperlink sends to a commit that used it so it induces people following the tutorial to use attrs which shouldn't be done anymore.

This commit replaces the link with the commit that replaced the attrs="" to the plain invisible="" use on the exact same button. (And adjusts the size of the delimiter to respect documentation guidelines.)
