dotenv_values returns an OrderedDict

From this example the value returned by dotenv_values is supposed to be a dict, but in reality (python 3.9) the value is of type OrderedDict:

from dotenv import dotenv_values

config = dotenv_values(".env")  # config = {"USER": "foo", "EMAIL": "foo@example.org"}

This is what I get:

from dotenv import dotenv_values

config = dotenv_values('.env') # config = OrderedDict([('consumer_key', '****'), ('consumer_secret', '****'), ('access_token', '****'), ('access_secret', '****')])

dict(config) # {'consumer_key': '****', 'consumer_secret': '****', 'access_token': '****', 'access_secret': '****'}

Start at the dotenv_values entry point and inspect how it constructs and returns the parsed configuration. Confirm the expected mapping type from the issue example, then add or update coverage so the result is a dict rather than an OrderedDict.
