Run against CI approved file on CI , local approved file on my local machine

[jmasonlee]

both machines are linux, so this isn't a difference in OS.

This is a bit more fuzzy... but I'd like to be able to specify which approved file my tests should be pointing at when I run them.

One approved file would be for CI, and one would be for my local devbox

try as_ci_specific_test() and see if this solves the issue https://github.com/approvals/ApprovalTests.Python/blob/main/approvaltests/namer/default_namer_factory.py#L37
