[BUG] Invalid packageManager is added to package.json

[cheesestringer]

What happened?

I'm using npm as my package manager of choice.
When I run commands like npm run dev or npm run build a new packageManager field with value pnpm is added to the package.json.

The packageManager shouldn't be guessed and it should be up to the user to add it to their package.json. Setting the value to npm@version will stop Plasmo interfering but this isn't something I'd want to include in my project until the field supports version ranges nodejs/corepack#95.
