Implement localization or remove the react-i18next dependency

The [dynamic plugin guidelines](https://access.redhat.com/documentation/en-us/openshift_container_platform/4.10/html/web_console/adding-dynamic-plugin-to-console) state that we should use `react-i18next` for localization, and the template repo we started with already had it installed. We currently still have it as a dependency but we are not using it (all text is just hard-coded in English).

We need to decide whether we will actually be doing localization. If so, we need to determine a process for that and implement it, and if not we should remove this dependency.
