fix: external contributors CI (#653)

## 📜 Description

Fix `size-diff` and `deploy-preview`.

## 💡 Motivation and Context

I hate to see failing PRs (especially when it's a false positive).

## 📢 Changelog

<!-- High level overview of important changes -->
<!-- For example: fixed status bar manipulation; added new types
declarations; -->
<!-- If your changes don't affect one of platform/language below - then
remove this platform/language -->

### CI

- split size-diff into two actions (with artifacts sharing);
- don't run deploy preview for forks;

## 🤔 How Has This Been Tested?

Can be tested only after PR merge.

## 📝 Checklist

- [x] CI successfully passed
- [x] I added new mocks and corresponding unit-tests if library API was
changed
