Fix test_coverage_active_file() for testthat 3.3

[jonthegeek]

Name snap_dir arg for testthat::local_snapshotter() in test_coverage_active_file()

Fixes #2630

It's a little ironic for this not to have test coverage, but the tests here are pretty light, and it's tricky to add them. I could probably get some things in place to at least throw errors if something like this happens again if you'd like.

Thank you. This has been annoying me for the past weeks. I got a local quickfix. Is there a chance to get this into the dev version quickly?

Hmmm, I haven't noticed this because I haven't updated devtools for a long time 😬

Let me also fix this in testthat, since I'm about to release it. We'll still want this change because it's definitely better practice to use a named argument here.

This is sort of nitpicky/meta but sort of legit and I know you are resilient enough @jonthegeek to take it 😁 but can you back out the Air-ish formatting changes, so this only has the meaningful change? I think it's just the addition of snap_dir =?

(I need to do a holistic re-formatting of devtools as a whole. And it really does make it easier to see what's in this PR / what the problem is.)

I almost did this earlier today because I didn't intentionally make them (air and/or "Strip trailing horizontal whitespace when saving" did). It's a little tricky to save WITHOUT applying those things but I can work it out!
