Upgrade Legacy schema to raido schema

[ardc-shorn]

When a user navigates to the "edit" page for a raid, if the raid is a legacy schema, the user is now prompted to "upgrade" the raid by providing the lead contributor orcid id.

When the user hits the upgrade button, the contributor will be added and the raid's "metadataSchema" field will be changed from LegacyMetadataSchemaV1 to RaidoMetadataSchemaV1.

When the "organisation" mandatory field is introduced, the upgrade screen will have to be changed to allow the user to enter the org - if that's not done, the upgrade endpoint will fail, telling the user that an organisation is required.

Feature is has been deployed to demo environment.
