Feature/ensure consistency in docs examples

This change focuses the CI Test job exclusively on the Ubuntu platform.
Given Valgo's reliance on Go's standard library and its independence
from operating system-specific functionalities.

This adjustment makes our CI process more efficient, reducing resource
consumption and build times without compromising the reliability or
coverage of our tests. It reflects our confidence in Go's cross-platform
compatibility for projects like ours that primarily utilize language
features and standard libraries.

This decision will be revisited periodically to ensure it continues to
align with the project's evolution and requirements.
