Bump minimum botocore version to 1.20.0 (ansible-collections#956)

[4.0.0] Bump minimum botocore version to 1.20.0

SUMMARY
With the next major version we can bump botocore/boto3 again.  Since 1.20.0 is now over a year old, we can bump the minimum version in preparation for 4.0.0.  CI should still test backports against the relevant versions for the backported release.
1.20.0 was released 2021-02-02.
1.21.0 was released 2021-07-15, hopefully we'll release 4.0.0 before July.
Should we release after mid-July we can always bump again.
( Follow up to ansible-collections#692 )
