update Allowing Connections link to v2 in SecurityGroup docs

[cameronsstone]

Update "Allowing Connections" link to v2 in SecurityGroup docs.

Before: https://docs.aws.amazon.com/cdk/api/latest/docs/aws-ec2-readme.html#allowing-connections

which doesn't exist in v2 docs (so gets redirected to the v1 docs).

After: https://docs.aws.amazon.com/cdk/api/latest/docs/aws-cdk-lib.aws_ec2-readme.html#allowing-connections
