Serialization.md needs a big overhaul

[vbatts]

Per #26 (comment) and
https://github.com/opencontainers/image-spec/issues?q=is%3Aissue+is%3Aopen+label%3A%22component%2Fserialization+spec%22

There is much cruft carried forward with the version that was cherry-picked for this image-spec.

moby/moby#22264

@vbatts I am ready to merge this improved doc after reviewing it. Are we blocked on that PR or can we merge it as-is and then add fixes as they go?

[vbatts]

hmm. i'm okay with merging and adding fixes as we/they go

[philips]

@vbatts you got dis or do you want me to do it? Lets wait a day or so to merge it.

[vbatts]

k. I'll open a PR

[philips]

@vbatts this stuff replaces the config in serialization.md?

[vbatts]

not so much replaces, but updates

[philips]

@vbatts are we waiting on anything or can this be closed out?

[philips]

Moving to v0.2.0 as I don't know what we are blocked on or what updates we need. Help would be appreciated @vbatts.

@vbatts moby/moby#22264 has been merged. So this should be easy?!

[philips]

The diff is very trivial from moby/moby#22264 to the OCI version and has no material changes. I am going to close this issue out and open a PR for the one wording improvement.
