Instead of only showing Choose FIRST FILE or just Choose show Choose 3 files when multiselect is enabled.

But it also change Choose FIRST FILE to Choose 1 file, no? Is that ok?

Nope, my bad, it does not. It’s weird that the multiversions has plural and singular but I suppose it’s needed for other languages.
