feat: make tests run in parallel

[LuizAsFight]

As the tests are the steps taking more time, now they run in parallel.

This PR also creates some internal ✅composite actions to use in our CI workflow yml files, making them cleaner and shorter.

New actions created: setup-node, setup-rust, setup-docker

To use them in a yml:

  end-to-end-test:
    name: Test E2E
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: ./.github/setup-node
      - uses: ./.github/setup-rust
      - uses: ./.github/setup-docker
        with:
          password: ${{ secrets.GITHUB_TOKEN }}

This helps avoiding a lot of duplicated code. To fix it I also tried to use:
❌ Reusable workflows - https://docs.github.com/en/actions/using-workflows/reusing-workflows - we're not able to use the same context after executing a reusable workflow, so we cannot use it to build envs. Which is our use case.
❌ Centralize env setup in a docker image - we run a docker environment (pnpm ci:test) to run the app, which would lead us to a Docker in Docker situation. Which is known to have several issues (https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/). Better to make it simples and avoid issues.

Closes #309

We can remove it if will not be required
