Fix discovery of tests under Windows

[cdprete]

Fixes the error reported in #5241 (comment)

Please be aware that some tests fail on Windows due to mismatches like

-   data-v-4727d85f=""
+   data-v-ee5aaf5b=""

(I've no clue what's that about)

and others fail due to localization issues

FAIL  utils/formatWithDataTypes.spec.ts > formatWithDataTypes > formats date from ISO string
AssertionError: expected 'Jun 1, 2024, 2:34:56 PM' to match /01\.06\.2024, 14:34:56/

Well, it seems like that hashes are created due to scoped styles (perfectly valid) and @reference (e.g.: @reference "../../../index.css";) is somehow breaking this because the paths somehow mismatch (i.e.: they don't use the @ alias as starting point).
I personally find those tests a bit fragile since the snapshots need to recomputed anything changes, but so be it. :)
Maybe the tests would be more stable/robust if a snapshot serialized would be added to drop the data-v-XYZ properties while doing the matching, but I can't of course decide this on my own.

Since I've no clue how to fix this in an absolutely safe way, I'll close this PR.

@SteKoe the main issue with the tests discovery on Windows is that in the includes an absolute path is provided.
Maybe you've an idea on how to adapt the config so that relative ones can be used instead.
