[BUG] warn Unknown user config "init.type". This will stop working in the next major version of npm

[styfle]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

I can use npm init -y and it works but there is a warning.

Expected Behavior

No warning and future versions should continue working.

Steps To Reproduce

echo "init.type=module" >> ~/.npmrc

npm init -y

Environment

• npm: 11.7.0
• Node.js: v22.22.0
• OS Name: macOS
• System Model Name: MacBook Pro
• npm config:

; "user" config from /Users/styfle/.npmrc

//registry.npmjs.org/:_authToken = (protected)
init.type = "module"

; node bin location = /usr/local/bin/node
; node version = v22.22.0
; npm local prefix = /Users/styfle/Code/foobar
; npm version = 11.7.0
; cwd = /Users/styfle/Code/foobar
; HOME = /Users/styfle
; Run `npm config ls -l` to show all defaults.

I would also like a way to omit the type field entirely - but init-type= and init-type=false don't work either.
