Make the contents of an S3 bucket deployed with CDK public

Files uploaded to an S3 bucket are not accessible by default from the Internet.

Which makes sense - by default they should be secure, but since we'd like to host a logo file to be displayed in our app, we need to make the bucket public.

Luckily, with CDK we need to literally change a single line of code - in this quick lesson we're going to learn how to make the contents of an S3 bucket public.
