refactor(tests): test-tabs-tab-bar-more-navigation-controller + scenario

[LKuchno]

Description

Moving test-tabs-tab-bar-more-navigation-controller into separate directory with scenario to it.

Closes: https://github.com/software-mansion/react-native-screens-labs/issues/1120

Changes

• Screen moved into a new directory with a corresponding name, extended with '-tab-bar-'
• New manual scenario created in the same directory covering different paths:
  - moving between More tab screen + tabs in it and tabs visible in tab bar normally,
  - check on navigation using buttons directly navigate to tabs and moretab screen
  - quick check on iPad when More tab is not displayed

I have few remarks. Let's resolve them before proceeding.

I have also a remark regarding naming. I think that more navigation controller has a broader scope than just tab bar, therefore I think that this rename is unnecessary here. What do you think?

I think we could add here test flows with resizing the app on iPad.

There is at least one more behaviour worth documenting.

When more navigation controller is selected on iPad (More list), and we resize the app, so that the "bottom tab bar" disappears, the previously selected tab is selected.

It would be ideal if we also were able to test navigation state updates in such case. Let's talk about this.
