Feature: Add install command

[YonicDev]

Motivation

The add command on pnpm (pnpm add), when supplied on its own, does not act like in other package managers do.

• For the other package managers, it acts as an alias to a package-less install command (i.e. installs all dependencies as defined in package.lock.json).
• In pnpm, it causes a command syntax error.

This PR solves this issue by adding the install command, which has consistent behavior between package managers. It also allows for a more semantically accurate markdown syntax.

Usage

<PackageManagers type="install" />

Resulting commands:

npm install
yarn install
pnpm install
bun install
ni

Super interesting, I don't think I've ever needed to document a pure install command but definitely a totally valid use case I missed.

Super thorough pull request, from code to tests and documentation. I only pushed a few nit pick changes, e.g. to update the changeset to follow the format I usually use and re-order some sections so we can release this right away.

Thanks a lot for your contribution 🙌
