Support pnpm

[Zamiell]

Hello,

It would be great if this library could support pnpm! In other words, the signature for the export should be changed from:

export default function convert(str: string, to: 'npm' | 'yarn'): string;

To:

export default function convert(str: string, to: 'npm' | 'yarn' | 'pnpm'): string;

From what I can gather, the syntax of pnpm is mostly the same as that of yarn. So this should be pretty easy.

For example:

• npm install foo --save --> yarn add foo
• npm install foo --save --> pnpm add foo

It's the same.

And:

• npm install foo -D --> yarn add foo -D
• npm install foo -D --> pnpm add foo -D

It's also the same.

However, there are some differences. For example:

• npm install foo --save-dev --> yarn add foo --dev
• npm install foo --save-dev --> pnpm add foo --save-dev

I'm by no means an expert in pnpm, so I'm sure there are more differences.

I dont think I have time right now, sorry, but I just wanted to raise the issue.

@Zamiell no problem! I don't quite have time right now either, but I'll mark this as a feature request.
