ci: optimize triggers for check mov files job (#1373)

## 📜 Description

Don't trigger `Check MOV files` for every commit.

## 💡 Motivation and Context

We should run that job ONLY if we added new `.mov` files. So I updated
paths to avoid unnecessary runs 🤞

## 📢 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

- add paths to `check-mov-files` job;

## 🤔 How Has This Been Tested?

Will be tested in subsequent PRs.

## 📝 Checklist

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