i18n and defineComponentBinds

[JohannesSchwegler]

Is your feature request related to a problem? Please describe.

Currently it is not possible to tell defineComponentBinds to use a different label for the error message placeholders.
For example is my key / path is named address.city, then the error message will say "address.city is required". UseField offers a way to add a custom label, defineComponentBinds doesn't.

Describe the solution you'd like

Provide the possibility to pass a custom label for message placeholders.
