`cargo insta test --all-targets` exits with an error when there are doctests

[ilyagr]

What happened?

Fortunately, the error occurs after all the tests are run. So, a human being looking at the output will know to ignore it. However, cargo-insta does exit with a non-zero error code in this situation.

Cc #438 and #408. With #438, adding --disable-nextest-doctest fixes the problem (though I wouldn't call this an elegant fix).

Reproduction steps

1. Clone https://github.com/martinvonz/jj/tree/3bbc3e5715eba28e79dad7528ccd8e9bc37b505b
2. Run cargo insta test --accept --workspace --all-targets --test-runner nextest
3. Observe the error at the end:

...
error: Can't mix --doc with other target selecting options
done: no snapshots to review
