Remove kubectl template dependency with simplified implementation (#4807

)

This PR removes the dependency on kubectl's template package by
providing a simplified implementation for CLI help text formatting.
Binary size reduced from `92M` to `81M`. The new implementation:

- Removes i18n support to reduce complexity
- Drops markdown processing (blackfriday) dependency  
- Keeps the core formatting functionality for command help text and
examples
- Maintains heredoc support for clean multiline strings
- Includes comprehensive tests

The result is a lighter, more focused package that handles just what we
need for CLI help formatting while removing a heavy dependency.

Original inspiration from kubectl is credited in the package
documentation.
