Investigate brittle e2e tests

[jrhoads]

Several(4) Cypress tests query the staging api for a specific repository 'datacite.test' and that repository must have the title "DataCite Test Repository". If this title is changed then the cypress tests will fail and we will not be able to do a Github Action based deployment.

The 4 tests are

cypress/e2e/client_admin/prefixes.test.ts#L33
cypress/e2e/client_admin/info.test.ts#L30,L74,L82,L90,L117
cypress/e2e/client_admin/settings.test.ts#L25
cypress/e2e/client_admin/doi.test.ts#L41

We should investigate whether there is a different way to approach this.
