Deleting browsing data dialog is too small

[fmarier]

Description

The "Delete browsing data" dialog box is too small and currently obscures the "Reset Brave Rewards data" link. This probably happened when the notice about search history was added in Chromium. It does however make it look like we are intentionally hiding this option behind a scrollbar.

Steps to reproduce

1. Open brave://settings/clearBrowserData

Actual result

Expected result

The scroll bar should not be present and the dialog box should be big enough to fit the extra link we add:
