cypress-downloadfile does not respect HTTP_PROXY value set

[noopurmath3]

Describe the bug
I am trying to use cypress-downloadfile to download a file on hitting a url. However, the url I am hitting is behind proxy, hence downloadfile is failing with 403 error. However, when I hit the same url that is behind proxy using cy.request it works as expected

To Reproduce
Steps to reproduce the behavior:

1. Try to download a file that is behind proxy using cy.download file
2. Even though HTTP_PROXY is set cy.download fails with. 403 error
3. However, the same url works when used as cy.request()
4. See stack trace:

cy.task('downloadFile') failed with the following error:
> request is not defined
