feat: don't add permission to the log subscribed lambda

[MarcioMeier]

Summary

After a few lambdas' logs subscribing to the same lambda and adding permission to that lambda, we'll get max policy size limit error.

So instead of we adding permission on our side, we are leaving the responsibility of managing the invoke permissions for the final user.

Breaking changes

• [X] The user must manage the invoke permission on his side
