Subject: [PATCH] Drop Yarn install commands in update message
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Yarn users should know how to translate from npm commands already as most packages document npm commands only. It’s also unfair to other package managers, like `pnpm` and `bun` that we don’t include them and I don’t want to maintain install commands for all of them.
