problem_statement: jwt.decode returns Signature has expired
I expect the decoded result of JWT, but it returns an error `Signature has expired`

## Reproduction Steps
```python
  import jwt

  try:
      payload: Dict = jwt.decode(token_obj[1], SECRET_KEY, algorithms=['HS256'], verify=True)
  except Exception as err:
      return JsonResponse(data={
          'message': err,
          'success': False,
      }, status=401)
```

## System Information

    $ python -m jwt.help

```json

{
  "cryptography": {
    "version": ""
  },
  "implementation": {
    "name": "CPython",
    "version": "3.6.12"
  },
  "platform": {
    "release": "4.19.121-linuxkit",
    "system": "Linux"
  },
  "pyjwt": {
    "version": "2.0.0"
  }
}
```
jwt.jws_api.PyJWS.decode_complete shouldn't accept kwargs argument
Here we are using flask_jwt_extended. There is a call in it that calls jwt.api_jwt.PyJWT.decode with a now disapeared parameter. The problem is that jwt.api_jwt.PyJWT.decode accepts any named parameters, and forwards them to jwt.jws_api.PyJWS.decode_complete. So a call that should fail is working but doing the wrong thing.

Moreover kwargs in jwt.jws_api.PyJWS.decode_complete isn't used at all. It looks suspicious.

## Expected Result

If an API caller calls a function with bad parameter, an exception is raised immediately. **kwargs shouldn't be used as garbage parameters collection.

## Actual Result

An exception is raised a few line later, masking the real problem of the wrong usage of the API

## Reproduction Steps

```python
import jwt
# does not raise even if prout has never been a valid parameter.
unverified_claims = jwt.decode(
        encoded_token, verify=False, prout="bar",
    )

```
