[BUG] Separator \n only outputs first changed file

[atorrescogollo]

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

When using separator: "\n", only the first line is kept in the step output.

To Reproduce

1. Use separator: "\n" with multiple changed files (more than one).
2. Echo the output from the next step.
3. In the latest step, you will only see the first changed file.

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04

Expected behavior?

Using separator: "\n" should set output correctly and retrieve all changed files, not only the first one.

Relevant log output

# -- STEP 1 --
> changed-files
... 
  All changed files: .terraform.lock.hcl
  testfolder with spaces/.terraform.lock.hcl
  testfolder1/.terraform.lock.hcl
  ...

# -- STEP 2 --
> echo "$CHANGED_FILES"
.terraform.lock.hcl

Anything else?

@atorrescogollo I’m a little skeptical about using URL encoded values to replace the separator since it would require decoding the output.

@atorrescogollo This should be available in the latest release.
