Cannot set both keepalive_timeout to None and force_close to True

[dnlserrano]

Describe the bug
Cannot set both keepalive_timeout to None and force_close to True in AioConfig.

This fails:

from aiobotocore import config
aioconfig = config.AioConfig(connector_args={'keepalive_timeout': None, 'force_close': True})

...
File ~/Repos/aiobotocore/aiobotocore/config.py:42, in AioConfig._validate_connector_args(connector_args)
     40 elif k in ['keepalive_timeout']:
     41     if not isinstance(v, (float, int)):
---> 42         raise ParamValidationError(
     43             report='{} value must be a float/int'.format(k))
     44 elif k == 'force_close':
     45     if not isinstance(v, bool):

ParamValidationError: Parameter validation failed:
keepalive_timeout value must be a float/int

But then the following also fails because aiohttp requires keepalive_timeout to be None when force_close is True:

from aiobotocore.session import get_session
from aiobotocore import config

aioconfig = config.AioConfig(connector_args={'keepalive_timeout': 12, 'force_close': True})

session = get_session()
async with session.create_client("s3", config=aioconfig) as client:
  await client.head_bucket(Bucket="mybucket")

...
File ~/.local/share/virtualenvs/aiobotocore-ab5i-gBl/lib/python3.10/site-packages/aiohttp/connector.py:219, in BaseConnector.__init__(self, keepalive_timeout, force_close, limit, limit_per_host, enable_cleanup_closed, loop)
    217 if force_close:
    218     if keepalive_timeout is not None and keepalive_timeout is not sentinel:
--> 219         raise ValueError(
    220             "keepalive_timeout cannot " "be set if force_close is True"
    221         )
    222 else:
    223     if keepalive_timeout is sentinel:

ValueError: keepalive_timeout cannot be set if force_close is True

Checklist

• I have reproduced in environment where pip check passes without errors
• I have provided pip freeze results
• I have provided sample code or detailed way to reproduce
• I have tried the same code in botocore to ensure this is an aiobotocore specific issue
• I have tried similar code in aiohttp to ensure this is is an aiobotocore specific issue
• I have checked the latest and older versions of aiobotocore/aiohttp/python to see if this is a regression / injection
