docker
the version property is deprecated
File: get-started/08_using_compose.md
The top-level attribute version is marked as DEPRECATED since beginning of 2021 and should be removed from the example of the compose documentation.

@ver-alex Would it be a good practice if we remove everything that includes about version?
I think it is confusing to use a deprecated attribute and should be removed. Version is not used anymore if you are on a recent and updated version of docker compose.
As the compose spec describes this here: https://github.com/compose-spec/compose-spec/blob/master/spec.md#version-top-level-element
Top-level version property is defined by the specification for backward compatibility but is only informative.
A Compose implementation SHOULD NOT use this version to select an exact schema to validate the Compose file, but prefer the most recent schema at the time it has been designed.
@ver-alex How about we change the version of docker-compose to the latest version?
Since the version element is (or should not be) used by the compose parser it has no functionality and is not a necessary part in a compose file anymore. I would just remove it. Guess that over time no compose files will have the version property. Also, since no version is stated, the documentation will not become outdated 😉.
