WP.com menu: Bring back "Plugins > Scheduled Updates" to classic sites

[mmtr]

Proposed changes:

The "Plugins > Scheduled Updates" menu was meant to be visible on sites with the default interface when it was first introduced, but we mistakenly added a "is classic interface" check in a follow-up that prevented the menu from being visible on such sites.

This PR restores the original behavior and ensures that the "Plugins > Scheduled Updates" menu is visible on sites with both the default and the classic interface.
