Write a stageless CI/CD pipeline using GitLab 14.2

Introduced the ability to create 'stageless' CI/CD pipelines in GitLab 14.2 by leveraging the `needs` keyword. This allows jobs to execute based solely on their defined dependencies, removing the requirement for explicit stages and enabling faster cycle times by skipping stage order. The post clarifies that stages are not being removed but that this provides an alternative for users who prefer dependency-based execution.
