fix: setup job to suport ssh github path in poetry (#368)

### Description

Reusable workflow fails in setup -> `modinput-test-prerequisites`
ignores `ssh://` protocol in poetry.lock/pyproject.toml

```
[tool.poetry.group.modinput.dependencies]
splunk_add_on_ucc_modinput_test = {git = "ssh://git@github.com/splunk/addonfactory-ucc-test.git", tag = "v0.2.0"}
pytest-xdist = ">=3.5.0"
```

Example Job:

```
  HangupException

  The remote server unexpectedly closed the connection.

      214│             if not sizestr:
    → 215│                 raise HangupException
      216│             size = int(sizestr, 16)
      217│             if size == 0 or size == 1:  # flush-pkt or delim-pkt
      218│                 if self.report_activity:
      219│                     self.report_activity(4, "read")

The following error occurred when trying to handle this error:


  HangupException
