Use the generic title "Front of identity document" instead of "Front of identity card"

[googol7]

See #8511

This change is similar to:

• https://github.com/stripe/stripe-ios/pull/3632/files#diff-2a6b2ccc2c3c46f603c78f8eba3e6f982503c9f60c1731ea09926a22671beff3R17-R23

Summary

Motivation

Because currently the title is always "Front of identity card" regardless of what is configured in options.document.allowed_types, users upload their "Identity card" (German: "Personalausweis") instead of the "Driver's license" (German: Führerschein"). So the more generic term "Identity document" should be used. This approach was also changed recently in stripe-ios here.

The optimal solution would be that the title corresponds exactly with options.document.allowed_types. This is how the web version already does it.

Example:

options.document.allowed_types	string used
["driving_license"]	<string name="stripe_front_of_dl">Front of driver\'s license</string>
["id_card"]	<string name="stripe_front_of_id">Front of identity card</string>
["passport"]	<string name="stripe_passport">Passport</string>
["driving_license", "id_card", "passport"]	<string name="stripe_front_of_id_document">Front of identity document</string>

I've seen that with this commit in the PR

• Update translations #8671

these new translations were added:

<string name="stripe_front_of_id_document">Front of identity document</string>
<string name="stripe_back_of_id_document">Back of identity document</string>

but they are not used in the code yet.

Testing
