Open manifest repo still points to old tenant location

https://code.vt.edu/it-common-platform/platform-support/apps/dashboard/-/blob/main/client/src/components/Namespaces/Dashboard/KustomizationCard.js#L73

This is fine for tenants that were created in code.vt.edu in the old tenants location, as it will just redirect to the new location. Any tenant that is created in the new location will result in the "Open manifest repo" link receiving a 404.
