Add an "advanced" article to describe how `relatedImages` and image digest pinning works. This includes the use of `RELATED_IMAGE_*` environment variables to digest pin operands deployed by the operator, which is not currently documented. Signed-off-by: Adam Kaplan <[email protected]>

Description of the change:
Add an "advanced" article to describe how
relatedImagesand image digest pinning works. This includes the use ofRELATED_IMAGE_*environment variables to digest pin operands deployed by the operator, which is not currently documented.Motivation for the change:
I was very confused by the behavior of
relatedImagesand digest pinning. For example - when attempting to setrelatedImagesin the base CSV manifest, I discovered thatoperator-sdk generate bundlewould always overwrite therelatedImagesfield in tree. It wasn't until I started iterating on a pull request (#6869) that I discovered there is an undocumented environment variable that lets operator authors define and wire in image digests for their operands.Checklist
