Translate the strings of Chat UI

To translate various strings in the UI, you need to pass the translation argument in the init function. Sample code looks like this:

  appId: APP_ID, 
  user: {
    id: USER_ID,
    displayName: USER_DISPLAY_NAME // optional
  ui: {
    theme: {
        primaryBackground: "#3f45ad",
        primaryText: "#ffffff",
        secondaryBackground: "#ffffff",
        secondaryText: "#000000",
        tertiaryBackground: "#f4f7f9",
        tertiaryText: "#263238"
    translation: {
