Make lazynpm package manager agnostic (pnpm, yarn support)

[ahkohd]

Is your feature request related to a problem? Please describe.
I don't use NPM; I mainly use PNPM and yarn

Describe the solution you'd like

• It should be able to detect automatically which package manager the project is using
• I should be able to set a package manager explicitly via the env variable. i.e
  NODE_PKG_MANAGER=yarn lazynpm or via argument i.e lazynpm --package-manager yarn

Describe alternatives you've considered
None

Additional context
None

Did you have any luck with pnpm or find out any information on whether the maintainer is open to that idea?

Would be great if it could detect the lockfile and use that aswell to pick a dielect automatically

@jesseduffield is this project dead? nothing happened for a long time.
If this project is dead, you should make it clear in the Readme or archive this.

Would've been an awesome addition to lazygit and lazydocker but without being package manager agnostic (I am using pnpm in one project and yarn in another) it's not usable.
