s2 / chore: add dynamic configuration protocol to spec website (#202)

## PR Checklist
- [ ] Linked issue added (e.g., `Fixes #123`)
- [x] I have run `bun run format` to ensure code is properly formatted
- [x] I have verified that `bun run lint` passes without errors
- [ ] If blog post was added:

(file names, folder names, and frontmatter)

## Summary
<!-- What has been updated and why -->
I've added the Dynamic Configuration Protocol to the website because
it's not deprecated and other specs link to it. I think we just forgot
to add it originally.
