docs: improve glab ci command docs 2
Description
This merge request improves the documentation for GitLab CLI pipeline commands by making the help text clearer and more consistent. The changes include:
- Better explanations: Command descriptions are simplified (like changing "Get JSON of a running CI/CD pipeline" to just "Get the details of a CI/CD pipeline") and more helpful usage examples are added throughout.
- Clearer options: Flag descriptions are rewritten to be more understandable, with better explanations of what each option does and when to use it.
- Consistent formatting: The documentation style is standardized across all pipeline-related commands for a more professional appearance.
- Enhanced guidance: Better explanations are provided for complex features like pipeline variables, inputs, and filtering options.
The changes don't modify any actual functionality. They only improve how the commands are documented and explained to users, making the CLI tool more accessible and easier to learn.
