GHSA-v4mq-x674-ff73: AWS Cloud Development Kit (AWS CDK) IAM OIDC custom resource allows connection to unauthorized OIDC provider

However, the current `tls.connect` method will always set `rejectUnauthorized: false` which is a potential security concern. CDK should follow the best practice and set `rejectUnauthorized: true`. However, this could be a breaking change for existing CDK applications and we should fix this with a feature flag. Note that this is marked as low severity Security advisory because the issuer url is provided by CDK users who define the CDK application. If they insist on connecting to a unauthorized OIDC provider, CDK should not disallow this. Additionally, the code block is run in a Lambda environment which mitigate the MITM attack. As a best practice, CDK should still fix this issue under a...
