Automatyzacja kopii zapasowej repozytorium na GitHubie

# Steps to make this workflow work
# 1. Create new repository with any default branch (it can just contain dummy readme.md file)
# 2. Generate PAT with repo priveleges
# 3. Add PAT as github secret in source repository
# 4. Add this workflow to source repository
# 5. Change whatever variables you want to change in this workflow (target repo with default branch and source branch are required)
# Disclaimer: This workflow doesn't copy any workflow files from source repository to target repository. It only copies source code.
