Fix schema dump on windows (#1123)

Without explicitly setting the encoding to "utf-8" I get the following error on windows (python 3.9)

```
  File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 115, in handle
    self.get_schema(schema, out, indent)
  File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 72, in get_schema
    self.save_graphql_file(out, schema)                                                                                   
  File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 59, in save_graphql_file      
    outfile.write(print_schema(schema.graphql_schema))                                                                    
  File "C:\Users\u\AppData\Local\Programs\Python\Python39\lib\encodings\cp1252.py", line 19, in encode 
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
```
