Review new default mode

[ptsefton]

• @rosanna-smith Check that this new mode works: https://github.com/Language-Research-Technology/ro-crate-editor-profiles/blob/default-mode-25/profiles/default-mode.json -- update descriptions if needed and any new props/classes you think would be useful
• @alvinsw and @moisbo Deploy as the default profile

My latest updates pushed to branch.

For updates still needed from @ptsefton (copied from Slack discussion):
Spec compliance: datePublished, publisher, name, description
Items to add: License, inLanguage
Author is missing description but don't know how often that actually gets used.
