Release testing instructions for the WooCommerce Stripe payment gateway 6.3.0

Undeprecate the Payment Request Button location filters

Verify that Payment Request Button filters continue to behave properly (showing or hiding the buttons):

1. Install the Code Snippets plugin on your test store.
2. Add a snippet with add_filter( 'wc_stripe_hide_payment_request_on_product_page', '__return_true' );
3. Make sure the PRB is hidden on product pages no matter which setting you use in the UI here (i.e. make sure the filter works as intended).
4. Make sure no deprecation notice is logged in the site's logs.

Other changes

• During critical flows, please look out for any unexpected formatting (due to some formatting changes in translated strings).
• In the setup flow (and gateway settings), verify that there are no unexpected styling issues.
