[Mobile Payments] Update StripeTerminal to 2.14

[joshheald]

Closes: #8086

Description

StripeTerminal 2.14 is required for Tap on Mobile work in sTAP Away. Updating to this version in the production version of the app will make the development process much easier, as we can't change dependencies based on feature flags.

Testing instructions

Run unit tests

Test card reader payment flows. I've checked the following:

Connection

• Connection during payment flow (take a payment with no connected reader)
• Connection from Payments menu
• Connection of a reader with a mandatory update: starts update process
• Connection of M2 reader
• Connection of WisePad 3 reader
• Connection of Chipper reader

Payment

• Take payment after in-line connection process
• Take payment with a previously-connected reader
• Take Interac payment
• Refund Interac payment
• Take contactless payment
• Take card-inserted payment

Update reader

• Reader update: error message when attempted with low battery
• Reader update: successfully updates software and starts payment (in that flow) when complete

---

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

LGTM! The only test I couldn't perform is the Interac refund, as I don't have the physical WisePad3 reader. I was also able to refund an Interac refund via the simulator 👍
