[Woo POS] Switch to dynamic card reader hint instead of hardcoded "Remove card" prompt

[samiuelson]

Closes: #13264

Description

This PR slightly changes the texts shown in the payment flow in POS.

The hardcoded "Remove card" hint has now been deleted in this PR in favor of relying on dynamic hints that come from Terminal SDK. This improves the experience in case the reader asks to insert card inside the reader or to enter PIN – the hardcoded "Remove card" hint turned out to be misleading when testing a UK-based store.

Steps to reproduce

1. Switch to UK-based store
2. Open POS (either by overriding conditions in WooPosIsEnabled or running WooPosActivity directly in AS)
3. Add to cart a product with price having decimals equal to .02 to emulate offline_pin_required terminal error.
4. Notice that POS shows text "Remove card", while reader asks to insert the card to the reader (confusing!)

Testing information

POS should not show hardcoded hints for payment states, rather the ones that come from payment state's readerHint property.

The tests that have been performed

I tested the card payment flow in POS for the UK-based store, for a total of 3.02 GBP. I verified that in case reader asks to insert the card, the "Please wait..." message is shown instead of "Remove card".
