fix from #8222 doesn't maintain scheme of replaced repo URL

Output of $ npm config get

; "user" config from /home/deck/.npmrc

prefix = "/home/deck/.local"

; node bin location = /usr/bin/node-22
; node version = v22.15.0
; npm local prefix = /home/deck/test
; npm version = 11.4.1
; cwd = /home/deck/test
; HOME = /home/deck
; Run `npm config ls -l` to show all defaults.

Steps to reproduce [in Linux bash]

mkdir ThisIsATest
cd ThisIsATest
rm -rf package.json package-lock.json node_modules ~/.npm
npm install is-number
rm -rf node_modules ~/.npm
npm --loglevel verbose install --registry=http://localhost:8080/artifactory/api/npm/all-npm/

Current Behavior

Eventually, you'll see....

npm http fetch GET https://localhost:8080/artifactory/api/npm/all-npm/is-number/-/is-number-7.0.0.tgz

Expected Behavior

npm http fetch GET http://localhost:8080/artifactory/api/npm/all-npm/is-number/-/is-number-7.0.0.tgz

Other Information

http://localhost:8080 doesn't exist but either way the issue still happens

If this is intentional / npm requires https:// repositories, please close this issue
