This GitHub Action copies files or folders from the current repository to a location in another repository

  Inspiration from @dmnemec
+ Uses rsync exclusively with full access to it's switches.
+ The rsync_option: makes it very versatile
+ with many configuration settings possible. 
+ If rsync_option: is not used it defaults to "-avrh"
! Use with caution!, test with –dry-run before actual commit.

+ Multiple source files/directories separated by comma
+ "file1.txt,file2.txt" or '"file 1.txt","file 2.txt"'
+ if there are spaces in the file/folder name(s)

+ Use ${{ github.event.head_commit.message }} to 
+ preserve the original commit message.

+ git-lfs support.

The API_TOKEN_GITHUB needs to be set in the Secrets section of your repository options. You can retrieve the API_TOKEN_GITHUB here (set the repo permissions). Fine-grained personal access tokens are much more secure as you can set access to only choosen repositories, You need Actions & Contents set to Access: Read and write & Metadata Access: Read-only
