QueryBuilder in ServiceClient.java doubles query parameter

Using the main branch, in the file ServiceClient the new buildQuery() method doubles the query params, because they are already contained in the given path.

public List<Participant> getParticipants(int offset, int limit) {

    if (limit == 0) {

        limit = 50;

    }

    Class<List<Participant>> reType = (Class<List<Participant>>)(Class<?>) List.class;

    return doGet(baseUrl + "/participants?offset={offset}&limit={limit}", Map.of("offset", offset, "limit", limit), reType);

}

leads to requets like

/participants?offset={offset}&limit={limit}?offset={offset}&limit={limit}

this is for /participants /users
