Need chairs to identify missing specs

We only have a few specs in our spec tracker: https://github.com/decentralized-identity/specs/blob/master/README.md

Let's identify and add missing ones

Note: this comes from https://github.com/decentralized-identity/org/blob/main/work-item-lifecycle.md#75-publication-and-submission

Start with the specs tracker in README.md and the publication and submission guidance in work-item-lifecycle.md. Compare the listed specs with the missing items identified by the chairs, then document and add the agreed missing entries; completion depends on chair review and agreement.
