Do you plan to unit test the change?

I am in general in favour of having unit tests, but this module has been explicitly disabled for coverage (https://github.com/canonical/github-runner-operator/blob/main/pyproject.toml#L15), and this is more of a bug fix for #351, so I am not sure its worth introducing a unit test for this small change.

I think for the e2e test and integration tests that uses the private-endpoint we should disable the aproxy of the private-endpoint self-hosted runners.
This will enable us to test this issue.
