Move the notifications preferences macros to the Internal category

The six macros that show the notification preferences are listed for every user in the Quick Actions menu and the Insert Macro dialog, in the Notifications category, next to the Notifications macro. They are only meant for the notification preferences of the user profile and of the wiki administration, which already include them, and they make little sense in a content page. Only the Internal and Deprecated categories hide a macro from these lists, for the users who do not display hidden pages.

The macros to change, each in the default categories of its wiki macro definition, in the notifications UI module:

• notificationsApplicationsPreferences
• notificationsAutoWatchPreferences
• notificationsCustomFiltersPreferences
• notificationsEmailPreferences
• notificationsFiltersPreferences
• notificationsSystemFiltersPreferences

notificationsFiltersPreferences is deprecated since XWIKI-18406, replaced by notificationsCustomFiltersPreferences and notificationsSystemFiltersPreferences, so the Deprecated category fits it better than Internal.

Steps to reproduce

1. Edit a page with the WYSIWYG editor.
2. Type {/notif}

Expected

Only the Notifications macro is listed, for a user who does not display hidden pages.

Actual

The six preferences macros are listed too, among them the deprecated notificationsFiltersPreferences, which is the first result for

KOs covered

Once these macros are hidden, the other usability problems found on them, in their descriptions, their Edit Macro dialog, their rendering in the editor and their documentation, no longer reach the users who insert macros. This issue therefore covers all their KOs:

Impact found on macro fluidity

These 62 KOs come from the WYSIWYG usability audit of the macros, under its usability criteria. The page of each macro, linked in the table, has the full notes. The category itself is criterion D3: the audit found that each of these macros should be in the Internal category.
