runner: nextest in insta.yaml not being obeyed

[Porges]

What happened?

I haven't figured out/looked deeply into why this is happening yet but runner: nextest in my insta.yaml is not being obeyed.

Reproduction steps

1. I have: <repo>/insta.yaml

test:
  runner: nextest

2. I run cargo insta test.
3. It does not use nextest.

I verified that the YAML is being parsed by corrupting it and ensuring that insta fails.

Insta Version

1.39.0

rustc Version

nightly

What did you expect?

The setting should be obeyed.
