Add api to retrieve localization

[Postremus]

Description

In my application I needed to retrieve the translations from keycloak.

I defined the themeapi myself, and used the restclientbuilder to invoke it. However, could this project maybe offer inbuild?

 @Produces(MediaType.APPLICATION_JSON)
    @Path("resources")
    interface ThemeAPI {

        @GET
        @Path("/{realm}/{themeType}/{locale}")
        List<KeySource> getLocalizationTexts(@PathParam("realm") String realmName, @QueryParam("theme") String theme,
                @PathParam("locale") String localeString, @PathParam("themeType") String themeType, @QueryParam("source") boolean showSource);
    }

@Postremus I belive this is already available? Can you check the admin console? The admin console uses admin REST API under the covers, so if the functionality is available in the admin console, it is available in admin REST API as well. It is maybe just calling proper endpoint might do the trick?

Yes, there is an API available, however it is not an admin rest api.

<keycloak-url>/resources/<realm>/<themeType>/<locale>

I did not find anything in the admin-client, or any of the other clients in this project, to access this resource.

I can access the realm localizations using keycloak.realm().localizations(). However, I would prefer to work directly with the effective translations.
