Update credit class metadata UI when C04 metadata gets fixed

[blushi]

Is your feature request related to a problem? Please describe. The C04 credit class metadata currently deployed on chain has some incorrect RDF uses in it / could be simplified. The front-end is currently set up to support that so it displays correctly in the UI for now but once the metadata is fixed, we should update the front-end too to reflect those changes.

Describe the solution you'd like

• We might want simplify regen:bufferPoolAccounts to be just a list, see https://github.com/regen-network/regen-registry-standards/pull/57#discussion_r1273358409 and relavant code in regen-web: https://github.com/regen-network/regen-web/pull/1980#discussion_r1273866144
• Within regen:bufferPoolAccounts, we use regen:walletAddress but this should be regen:address, see https://github.com/regen-network/regen-registry-standards/pull/57#discussion_r1273358947 and https://github.com/regen-network/regen-web/pull/1980#discussion_r1273866421
• We should check for schema:Duration equality for parsing duration values: https://github.com/regen-network/regen-web/pull/1980#discussion_r1274493096
