ssl_verify=false doesn't work in dvc version 2.6.4

[albreand]

When having ssl_verify set to false and executing dvc pull i get this error:

dvc pull
ERROR: unexpected error - verify_ssl, ssl_context, fingerprint and ssl parameters are mutually exclusive 

With the Version 2.0.17 we did not have this issue.

For better replicability:

$ dvc pull -v

Reported to aiobotocore at aio-libs/aiobotocore#883

For the record: the fix got merged and released in aiobotocore, but s3fs is pinned for now to the older one fsspec/s3fs#528 🙁

[dberenbaum]

Looks like s3fs is now on aiobotocore 2.4.0 in https://github.com/fsspec/s3fs/blob/main/requirements.txt
