fix: Examples stopped to work after RN issue (#1632)

## Description

See: facebook/react-native#35210 for
explanation why fixes are needed and why they look like it.



## Changes

Followed recommendations included in aforementioned issue.

* `FabricTestExample`: upgraded `React Native` to `0.70.5`
* `FabricExample`: upgraded `React Native` to `0.70.5`
* `Example`: upgraded `React Native` to `0.66.5`
* `TestsExample`: upgraded `React Native` to `0.70.5`

* `TVOSExample`: ??? Need to check whether it is affected


So `Test iOS build` CI fails due to [mismatched versions of
`hermes-engine` in `Podfile.lock` and version in
"snapshot"](https://github.com/software-mansion/react-native-screens/actions/runs/3435966238/jobs/5728946474).
Locally everything works fine, I updated pods, and have also run `pod
update hermes-engine --no-repo-update` and pushed all results -- it did
not help.

Since this is second time the problem occurs I decided to with similar
solution as earlier
[958b472](958b472)

I do not like this fix, but I do not find any other way to solve this.

## Test code and steps to reproduce

See that CI passes
