Installing via pnpm will not load plugins

[eldair]

Environments:

• Prettier Version: 2.8.7
• Running Prettier via: vscode
• Runtime: vscode, nodejs 19.8.1
• Operating System: wsl2 - ubuntu
• Prettier plugins (if any): @prettier/plugin-php

Steps to reproduce:

Project with prettier and @prettier/plugin-php installed via pnpm

Expected behavior:

Can format php files with prettier

Actual behavior:

Prettier cannot format php files - plugin not detected

Using pnpm to install deps breaks prettier plugins. Adding php-plugin to prettierrc doesn't fix the issue.
