Removing the "Refresh" button under the donate modal

[kjozwiak]

Description

Under the direct donations modal, there's a refresh button next to Make this monthly which basically does the exact same thing as clicking on the checkbox. I think we should remove this as it's pretty confusing. In this context, I'm not sure if the "refresh" button is the correct image to use.

Similar to issue #1598.

Steps to Reproduce

1. open dev or beta and enable rewards via brave://rewards
2. once enabled, visit a website and make sure it's added into the contribution table
3. visit the same website and click on the Rewards button in the URL -> Donate Now
4. click on the refresh button next to Make this monthly a few times
5. click on the checkmark/checkbox button next to Make this monthly a few times

Actual result:

Expected result:

Personally think the refresh button should be removed in this case as it doesn't really make sense. There's already a clickable checkbox to the left. You basically have the same functionality on the left and right of the Make this monthly text.
