SearchUI:Move 'Find Contacts' upgrader steps from AdminUI to SearchUI

[aydun]

Overview

Fixes issue raised in #26669 by moving the 'Find Contacts' search from AdminUI to SearchUI

Before

The search was moved to SearchUI but AdminUI still changed the menu.

After

World peace is restored.

Technical Details

Also changes the path from 'civicrm/adminui/search/contacts' to 'civicrm/searchui/search/contacts'

Comments

If AdminUI is enabled on a version with Find Contacts but SearchUI is not enabled, the menu will point to the modified, invalid link. A simple fix is to enable and disable SearchUI. Alternatively just leave SearchUI enabled as it currently provides this 'Find Contacts' search and others under an 'Experimental' menu.

• A great way to speed up this process is to "trade reviews" with someone - find an open PR that you feel able to review, and leave a comment like "I'm reviewing this now, could you please review mine?" (include a link to yours). You don't have to wait for a response to get started (and you don't have to stop at one!) the more you review, the faster this process goes for everyone 😄
