Reproduction steps

1. Use NPM_CONFIG_USERCONFIG=/tmp/custom.npmrc with authentication inside for a private repo and pnpm v10.33.2
2. Upgrade pnpm to v11
3. Rename NPM_CONFIG_USERCONFIG to PNPM_CONFIG_USERCONFIG as mentioned in the migration guide/breaking changes.

Describe the Bug

I've renamed NPM_CONFIG_USERCONFIG to PNPM_CONFIG_USERCONFIG as it was mentioned in the migration guide and breaking changes, but it doesn't work. I haven't found a way to make pnpm v11 read a custom .npmrc file using environment variables (tried pnpm_config_npmrcauthfile, pnpm_config_npmrc_auth_file). It's not clear how to do that from the documentation.

Expected Behavior

• Renamed environment variable does work as expected.
• Documentation has a clear example of how to use a custom path to the .npmrc file.
