fix: message props update without button teardown

[danzhaaspaypal]

There was a bug where updating button message properties such as amount would tear down then rebuild the entire button component to render the new message. This fix allows just the message to rerender and preserves the button.

Testing instructions:

Setup

• open this paypal-js PR locally
• execute npm run build in paypal-js
• open paypal-js file explorer to packages/react-paypal-js/dist and copy the cjs and esm directories
• open this lighthouse-ecommerce AKA "Palmart" PR locally
• run npm install
• open Palmart file explorer to node_modules/@paypal/react-paypal-js/dist
• delete the cjs and esm directories
• paste copied cjs and esm directories there
• delete .next directory (previous node_module builds are cached there, and we do not want to use those)
• execute npm run dev
  • if it does not launch and gives node: --openssl-legacy-provider is not allowed in NODE_OPTIONS, you must first set the node version to the version specified in the .nvmrc file

Validation

• go to a product page and change the item quantity. The button message quantity should update but not tear down the buttons.
