[MOBILESDK-2482] Apply appearance API typography to dialog buttons

[cttsai-stripe]

Summary

Apply appearance API typography to dialog buttons by assigning correct style.

Typography.body1 is used instead of Typography.button because the former utilizes the Appearance API, whereas the latter does not.

Motivation

Buttons in remove saved PM dialog don't use appearance API typography

Can you add another test here for the crazy appearance?

[jaynewstrom-stripe]

I think you can replace this with PaymentSheetAppearance.entries

We probably want all the font sizes too.
