Makes the scanned name and expiry date of a card publicly visible

[via-guy]

Summary

Remove @_spi for ScannedCard properties.
Fixes #2484 and #2875

Motivation

In order to autofill our card entry form we need the scanned details, but for some reason they're blocked from being publicly visible.

Testing

It wasn't... I just unblocked some basic properties.

Changelog

[Changed] ScannedCard to allow access for expiryMonth, expiryYear and name.

Is this getting updated soon? Would love to get all available data from the scanned card, but the spi properties don't allow it.

@kgaidis-stripe can you please have a look at this? It would really help out a lot of people.

[via-guy]

@kgaidis-stripe I know this isn't a critical issue so no rush, but would love to push this tiny PR forward.
