docs(file-upload): fix an inaccuracy in the Multiple files example

dmshvetsov · web-flow · commit edb47d69bfa4 · 2021-08-12T08:00:05.000+03:00
When the Multer fields method is used Multer returns an object with field names as keys and `File[]` as values.

In the Multiple files code example injected `files` are just `File[]`.
