update to add that crane retains the digest

[csantanapr]

Found about this little secret on Knative Slack channel that crane copy retains the digest value when copying images
Very important to know for some uses cases around security and secure supply chain

The markdown is generated, you'll want to update the source of truth here:

go-containerregistry/cmd/crane/cmd/copy.go

Line 27 in 162d96e

Short: "Efficiently copy a remote image from src to dst",

Thanks @imjasonh , updated the go file now

[imjasonh]

You'll need to run ./hack/update-codegen.sh now to get the markdown generated from the Go code. Sorry for all the hoops to jump through.

@imjasonh You're telling me that contributors to help out with markdown docs need to install Go and run Go on their computers? 🤣
You Go/k8s folks really love generators ❤️

[csantanapr]

@imjasonh I submitted the code-gen results, I used Go version 1.16 hope is ok with that version

[imjasonh]

Yep! It's not ideal, but honestly I think this is the first time someone's contributed to these docs that wasn't already a contributor.

Thanks for putting up with it! ❤️
