chore(deps-dev): add yarn binary in the repo

[trivikr]

Issue

Internal JS-5639

Description

Uses vendored yarn version, as downloading yarn sometimes throw network errors failing internal builds

Testing

This check verifies that globally install yarn classic is able to jump to yarn modern.
We'll remove corepack from internal CI in future commit. We'll retain packageManager field for reference.

Pre-requisites

Fresh installation of Node.js (uses npm), and globally install yarn classic

$ rm -rf ~/.nvm

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

$ nvm ls
            N/A
...

$ nvm install 20
...
Now using node v20.18.1 (npm v10.8.2)
Creating default alias: default -> 20 (-> v20.18.1)

$ node -v
v20.18.1

$ npm install -g yarn

Download aws-sdk-js-v3 main branch and yarnPath branch with network enabled.

$ git clone https://github.com/trivikr/aws-sdk-js-v3.git --single-branch --depth 1

$ cd aws-sdk-js-v3

$ aws-sdk-js-v3> git fetch origin yarnPath:yarnPath --depth 1

Run the following commands with network disabled

Before

Throws error since network is not available to download yarn

$ aws-sdk-js-v3> yarn --version
1.22.22

In CI, it uses [email protected] as corepack is enabled

After

The globally installed yarn classic jumps to locally provided [email protected]

$ aws-sdk-js-v3> git checkout yarnPath

$ aws-sdk-js-v3> yarn --version
4.5.1

If corepack is enabled, it'll just download [email protected] from registry

$ aws-sdk-js-v3> corepack enable

$ aws-sdk-js-v3> yarn --version  
! Corepack is about to download https://repo.yarnpkg.com/4.5.1/packages/yarnpkg-cli/bin/yarn.js
? Do you want to continue? [Y/n] Y

4.5.1
