incorrect docs on tars attribute in oci_image #853
Description
The explaination of why the tars list should not be sorted in https://github.com/bazel-contrib/rules_oci/blob/main/docs/image.md?plain=1#L82
is not correct, (Dockerfile cargo-culting?)
List of tar files to add to the image as layers. Do not sort this list; the order is preserved in the resulting image. Less-frequently changed files belong in lower layers to reduce the network bandwidth required to pull and push.
The order only affects file shadowing, when running the image as a container. (well and the tiny manifest which holds the list of layers)
Tried to rephrase in a PR, but it gets complicated and my tech writing skill are not that good.
Also 'lower' is problematic - the lowest layer would be the first layer in the overlay fs - but that is un-intutive when looking a list of tars separated with newlines
