[CI] Refactor yarn-install composite action (#9613)

# Introduction
Unless I'm mistaken in the existing `yarn-install` composite action
`dependencies` are cached twice.

## Cached through `setup-node`
As we're providing `yarn` value to cache inputs.
Setup node will cache the global `.yarn`
```yml
    - name: Setup Node.js and get yarn cache
      uses: actions/setup-node@v3
      with:
        node-version: 18
        cache: yarn
```

## Programmatic `node_modules` caching
We even manually still cache `node_modules` folder using:
```yml
    - name: Cache node modules
      id: node-modules-cache
      uses: actions/cache@v3
      with:
        path: |
          node_modules
          packages/*/node_modules
        key: root-node_modules-${{ hashFiles('yarn.lock') }}
        restore-keys: root-node_modules-
```
By the way it seems like that the `yarn.lock` file is useless as the
restore-key pattern omits it
This could, unless I'm mistaken, leads to invalid cache restore

## Runtime
The current infra results in the following install deps logs:

## Suggestion
We should stick to only one deps caching mechanism.
Also caching the node_modules folder is not
[recommended](611465405c/examples.md (node---npm)).
That's why I would factorize our caching to the `setup-node` scope only.

## The cache-primary-key crafting
Within the cache-primary-key we will inject the following metrics:
- Node version, as we're caching `node_modules` directly in this way to
avoid cache desync in case we upgrade node.
- Hash of the lockfile, in this way if the lockfile comes to mutate we
will re-install the deps from scratch, in this way no need to
programmatically listen for `changed-files` on the `package.json` and
the `lockfile`
- Strict installation with `check-cache` and `enableHardenedMode` to
true and obviously the `--immutable` flag ( note adding the
`--immutable-cache` by principle even if on paper is overkill as a cache
restoration and install should never occurs )
