[10.x] Add missing putFile to Filesystem contract

[rihardsgrislis]

Hey,

Storage::disk('custom')->putFile(
    'custom',
    new File("/tmp/{$filename}"),
    "{$client->id}_{$client->name}/{$filename}"
);

Since disk method returns \Illuminate\Contracts\Filesystem\Filesystem Intellisense is yelling at me for using putFile because the contract is missing it. Copied the method header from:

framework/src/Illuminate/Filesystem/FilesystemAdapter.php

Line 388 in f7c57c4

public function putFile($path, $file = null, $options = [])

Are there any implications for adding this method to the contract?

Can't add to a contract on a patch release.
