[5.2] Adjust the links for more details within the HTTP Header Plugin

[zero-24]

Summary of Changes

Adjust the links for more details within the HTTP Header Plugin

Testing Instructions

Check the Configuration Options for the Strict-Transport-Security within the plugin before and after the patch

Actual result BEFORE applying this Pull Request

The hsts preload list is linked from the first option which is not quite correct as that site is only relevant when the preload option is set.

Expected result AFTER applying this Pull Request

The main header links to the mozilla MDN and the hsts preload page is linked from the preload setting only which makes more sense.
