Try to fix lsf-bandwidth issue in development

[minevala]

Description

• Decrease the bandwidth size of Github actions by replacing the file comparison with a file name-hash-based cache key.

Closes

• https://helsinkisolutionoffice.atlassian.net/browse/HDS-858

Motivation and Context

• All Github actions are failing with error:
  batch response: This repository is over its data quota. Account responsible for LFS bandwidth should purchase more data packs to restore access
• We create a file name-hash-based cache key without pulling the actual images every time. We can use the ones in Github's actions cache instead
• The solution: Cache for LFS actions/checkout#165 (comment)
• The origin for solution: https://www.develer.com/en/avoiding-git-lfs-bandiwdth-waste-with-github-and-circleci/
