WordAds: text under Terms of Service should be on one line to avoid confusion that there is a missing second checkbox

**What**
If you take a look at the bottom of the WordPress.com > My Sites > Tools > Earn > View Ad Dashboard > Settings, the text below `Terms of Service` is on two lines.

**Why**
One could think that there should be a second checkbox below the first one but that is missing for some reason.

**How**
Placing the text `I have read and agree to the Automattic Ads Terms of Service.` and `I agree to post only family-friendly content and will not purchase non-human traffic.` on one line will avoid such confusion.

Open WordPress.com > My Sites > Tools > Earn > View Ad Dashboard > Settings and inspect the Terms of Service section shown in the linked screenshot. Verify how the two consent sentences are laid out and confirm that both render on one line without suggesting a missing second checkbox.
