docs: defining TBC stages is no longer required

    We chose to keep those names anyway to stay compatible with GitLab Auto DevOps that has the same philosophy.

Your `.gitlab-ci.yml` file will have to declare **all stages required by included templates**, in the right order.

!!! question "Can I add my own stages?"

!!! TIP

    If you're only using the generic _to be continuous_ pipeline stages, you won't have anything to do as all our templates 

    define those stages for you.

    Instead of keeping track of required stages, simply **add them all** in your `.gitlab-ci.yml`:

    But if you're willing to add you own, then you'll have to override the stages in your `.gitlab-ci.yml` file, 

    **inserting yours**:

    ```yaml

    stages:

      - infra

      - deploy

      - acceptance

      - my-pre-publish # 👈 insert your extra stage(s)

      - publish

      - infra-prod

      - production
