Some editor buttons of the Cart and Checkout blocks inherit the theme styling when they shouldn't

[Aljullu]

To reproduce

0. Make sure you don't have any payment method set up.
1. Install TT3 and go to Appearance > Editor > edit one of the templates > Styles (white and black circle on the top right) > Browse Styles and select the Whisper style.
2. Create a post or page and add the Cart and Checkout blocks.
3. Notice some of the buttons inherit the theme styling (text color, borders, etc.), making them difficult to read:

Expected behavior

Buttons displayed in this kind of notices shouldn't inherit the theme styling.

"Configure payments methods" is a link styled to be displayed as a button.

We have Setup a Terms and Conditions page and Setup a Privacy Policy page buttons for the internal actions on the checkout block page. However, they're not styled like a blue wp-admin button.

The goal is to have them as links to be styled as a blue wp-admin button that doesn't inherit any theme style:

• Configure payment method
• Setup a Terms and Conditions page
• Setup a Privacy Policy page

We will now convert the Configure payment method link to a button. And later, we will convert all the above to a link styled as a button. Ticket for it: #8944

I'm adding this ticket to Global styles Epic to convert the Configure payment method link to a button, as it will need a separate PR.

We will now convert the Configure payment method link to a button.

I don't think we should mess with the semantics here; it is a link. What we can do is make it match the links in the inspector, where we have a small arrow icon beside a link to another admin page.
