Remove line from "Delete site data?" modal that is not applicable

[LaurenWags]

Description

When clearing data from the site details page of settings, there's a line that says "Data that affects ad personalization is deleted". This comes from Chromium and Brave Ads does not factor in - since it's not applicable to Brave Ads this line should be removed.

Steps to reproduce

1. Clean profile (either 1.71.123 with C130 or 1.73.89 with C131)
2. Close/relaunch to pull griffin
3. Navigate to a site (ex. https://www.whatarecookies.com/cookietest.asp)
4. After site loads, click on the "tune" icon in the URL bar and select "Site settings"
5. Click the "Delete data" button
6. See modal
