New Buttons Progress Bar for Default V2

[JaneSjs]

T15274 - Change the survey progress bar style https://surveyjs.answerdesk.io/internal/ticket/details/T15274

---

The task is to modify the progress bar appearance:

import "survey-core/defaultV2.min.css";
import "survey-core/modern.min.css";

const modernProgressBarCss = {
  progress: "sv-progress sv-body__progress",
  progressBar: "sv-progress__bar",
  progressText: "sv-progress__text",
  progressTextInBar: "sv-hidden",
  progressButtonsContainerCenter: "sv_progress-buttons__container-center",
  progressButtonsContainer: "sv_progress-buttons__container",
  progressButtonsImageButtonLeft: "sv_progress-buttons__image-button-left",
  progressButtonsImageButtonRight: "sv_progress-buttons__image-button-right",
  progressButtonsImageButtonHidden: "sv_progress-buttons__image-button--hidden",
  progressButtonsListContainer: "sv_progress-buttons__list-container",
  progressButtonsList: "sv_progress-buttons__list",
  progressButtonsListElementPassed: "sv_progress-buttons__list-element--passed",
  progressButtonsListElementCurrent:
    "sv_progress-buttons__list-element--current",
  progressButtonsListElementNonClickable:
    "sv_progress-buttons__list-element--nonclickable",
  progressButtonsPageTitle: "sv_progress-buttons__page-title",
  progressButtonsPageDescription: "sv_progress-buttons__page-description"
};
 survey.css = modernProgressBarCss;

It works for a SurveyJS Form Library: https://codesandbox.io/s/long-cookies-thn8m7?file=/src/SurveyComponent.jsx. For a Survey Creator, custom CSS is not applied: https://codesandbox.io/s/ecstatic-scooby-7zndc2?file=/src/SurveyCreatorComponent.jsx:1742-1933
