docs: update prints in documentation

[AlessandroPomponio]

Summary

This PR refreshes the documentation to reflect the current state of the ado CLI and codebase. Terminal output blocks, command examples, and YAML snippets across several pages have been updated to match what users actually see when running ado today, replacing outdated content that no longer matched real CLI behaviour.

High-level Changes

• CLI output blocks updated: Terminal and command output examples in the user guide and developer guide now show current ado CLI output, including updated column names, version numbers, and actuator/operator listings.
• Commands updated to recommended forms: Documentation now consistently recommends the --details flag for ado get actuators and ado get experiments, and uses --use-latest in operator workflow steps.
• YAML snippets replaced with live includes: Hardcoded YAML examples for pyproject.toml and sample store configuration are now included directly from their source files, keeping those documentation pages automatically in sync.
• Formatting fixes: Various minor markdown formatting issues corrected, including admonition syntax, code block style directives, and list indentation.
• ray-tune defaults updated: Default parameter values in the ray-tune operator documentation corrected to match current behaviour (NaN, null, bayesopt).

Impact

Documentation only — no source code or behaviour is changed. Users following the updated pages will now see commands and outputs that match the current version of ado.
