Documentation: PHP Warning using 7.3

[dannylamb]

Getting this nagging warning on ISLE for Islandora 8. We're using PHP 7.3 and are getting this:

Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /var/www/html/web/modules/contrib/islandora/src/EventSubscriber/LinkHeaderSubscriber.php on line 286

I think we discussed this before, but for reference. https://wiki.php.net/rfc/continue_on_switch_deprecation

It's eerily similar to another 7.3 warning I fixed recently.

Wait what will happen with 7.4 ;-)
