Context

This PR adds more example to the artifact_sources Step input.

Changes

• update step.yml
• update examples.md
• E2E test fix:

The directory transfer E2E tests were failing, with this error:

actual:
.
└── hello_world.txt
1 directory, 1 file

expected:
.
└── hello_world.txt
0 directories, 1 file

This test case should ensure that the transferred directory layout matches to the original layout. For some reason the originally executed tree command in the artifact producer pipeline, printed a different report at the end of the tree listing, than what we get if execute the same command today (1 directory, 1 file vs 0 directories, 1 file). This is likely due to a version difference between the tree commands. One version included the source directory in the report, while the other didn't.
The fix involved updating the artifact producer pipeline, running a new pipeline build, and based on that, updating the step's E2E tests.
