checkoutBrandingUpsert
Updates the checkout branding settings for a
[checkout profile](https://shopify.dev/api/admin-graphql/unstable/queries/checkoutProfile).
If the settings don't exist, then new settings are created. The checkout branding settings applied to a
published checkout profile will be immediately visible within the store's checkout. The checkout branding
settings applied to a draft checkout profile could be previewed within the admin checkout editor.
To learn more about updating checkout branding settings, refer to the checkout branding
[tutorial](https://shopify.dev/docs/apps/checkout/styling).
