Use Github Action to push directly to main

Usually the default branch main is blocked to keep save the code and ensure devs are merging from PRs with the right automated checks. However, sometimes there are some automations we rely a 100% to update our default branch, to be able to keep main protected and securely push changes direct to that branch from the execution of a Github Workflow use the following configuration steps:

1. Ensure your repo has a rule already protecting your default branch. Check it trying to push any change directly, or even reviewing the list of rules configured in your repository at Settings --> Rules --> Rulesets.
2. Add a bypass condition to the rule that is blocking pushes to default branch, add the Deploy keys there and save.
3. Go and create a Deploy key using a public key of a SSH key your can create locally with ssh-keygen command.
4. Configure a secret for your repo using as value the private key of the same SSH key, you can call it DEPLOY_KEY.
5. Configure the git checkout step in your workflow to use the deploy key:

   [...]
         - name: Checkout code
            uses: actions/checkout@v3
            with:
              ssh-key: ${{ secrets.DEPLOY_KEY }}
   [...]

6. Now test the process of pushing directly to your main branch.
