Add ror & fundref IdentifierSchemes to db/seeds.rb

Used the same values from `task add_new_identifier_schemes` and `task contextualize_identifier_schemes` (see `lib/tasks/upgrade.rake`) for adding seeds.
- However,  `fundref.identifier_prefix = 'https://doi.org/10.13039/'` doesn't seem to be correct in `lib/tasks/upgrade.rake`.
  - "https://api.crossref.org/funders/" is used in DMP Assistant's DB, so that was used instead.
