public method for tab focus from agent

[32teeth]

Problem

Without user intent you cannot switch to a different tab
https://aws.github.io/mynah-ui/api-doc/classes/MynahUI.html#selectTab

Using mynah-ui in vs code extension there is not currently available a good way to have a notification callback command select a tab if many are open and the responding message is not in the currently focused tab

User Story: If i have many tabs in the mynah chat in vs code open, and one that receives a response that generates a vs code notification, i would like to be able to click the notification and refocus on said tab

Expected behavior

Add setFocusTab as a public member of mynah class that can deterministically set focus on the specific tab without having an eventId (it can generate one) retaining eventId as private generated id

   * This function is used to select a tab with the given generated ID.
   * If the tab does not exist, it will not select any tab.
   * This function is useful when you want to select a tab with a known ID, yet without user interaction.
   * for example, in response to a message from the chat, which produces a notification and the tab currently selected is not the one that the notification is related to.

  public setFocusTab = (tabId: string): void => {
    if (MynahUITabsStore.getInstance().getTab(tabId) !== null) {
      const eventId = this.getUserEventId();
      this.selectTab(tabId, eventId);
    }
  };

The eventId check is removed from the selectTab method. Please use selectTab method from the main class instance.
