[PATCH] ci: fix unit tests not running on windows

Since 3141df7ec4 (ci: don't skip smallest test slice in GitLab,
2026-02-19) both our CI workflows at GitLab and GitHub use one-indexed
slices to run windows tests. Modify the check for running unit tests on
Windows to also be one-indexed as otherwise, the unit tests are never
run.

windows, 2026-09-17), with Johannes's cargo fixes [1] merged in.
