Test scripts in package.json fail on Windows

Bug

Describe the bug

On Windows running the test scripts in package.json fail as setting the environment variables only works on Linux:

    "test-debug": "NODE_OPTIONS=--import=extensionless/register vitest --inspect-brk --no-file-parallelism",
    "test-watch": "NODE_OPTIONS=--import=extensionless/register vitest",
    "test": "NODE_OPTIONS=--import=extensionless/register vitest run

https://github.com/geostyler/geostyler-qgis-parser/blob/23679aea86c6cf63517f3697422f20db0204c2ef/package.json#L46C1-L48C70

For example:

npm run test-debug

> [email protected] test-debug
> NODE_OPTIONS=--import=extensionless/register vitest --inspect-brk --no-file-parallelism

'NODE_OPTIONS' is not recognized as an internal or external command,
operable program or batch file.

One previous suggestion was to use cross-env:

npm install cross-env
# in package.json you then need to use:
    "test": "cross-env NODE_OPTIONS=--import=extensionless/register vitest run"

This approach still works but this now an archived project. Any ideas on a cleaner long-term solution?
