Fix vertical alignment of Last Synced label in Settings header

[Copilot]

The "Last synced" label in the Settings editor header was vertically misaligned with the adjacent "Edit as JSON" button due to padding-top: 7px on .last-synced-label interfering with the parent flexbox container's align-items: center.

Removed the conflicting padding. The parent .settings-right-controls flex container now properly centers both elements.

Changed:

• src/vs/workbench/contrib/preferences/browser/media/settingsEditor2.css - Removed padding-top: 7px from .last-synced-label
