fixes npm citgm tests that pull source code using repository

[reggi]

https://github.com/nodejs/citgm/issues/1092

an old repo link like github.com/maxogden/binary-split will redirect to the new one, but for some reason the old codeload.github.com link won't redirect to the new repo.

This is because the source code for binary-split is being fetched from (which is 404): https://codeload.github.com/maxogden/binary-split/tar.gz/47044d430f5973380bfd4ef3d179f9d5f3eb54b4

we use the repo link to fetch the source when we run CITGM https://github.com/npm/cli/blob/latest/.github/workflows/node-integration.yml#L326
