Description

When running openapi-fetch I get a Failed to read _auth from ~/.npmrc error.

My .npmrc file has the new _auth syntax, which is how it is configured on NodeJS v20:

//registry.npmjs.org/:_auth=<auth_token>

Feels like openapi-generator is not supporting the newer _auth syntax for NodeJS v20?

If I run it with NodeJS v16 and the old _auth=<auth_token> syntax, it works

openapi-generator version

2.16.3 on my package.json

"@openapitools/openapi-generator-cli": "^2.16.3",

Steps to reproduce
