ref to
https://docs.docker.com/compose/intro/history/#docker-compose-cli-versioning
> Version one of the Docker Compose command-line binary was first
released in 2014. It was written in Python, and is invoked with
docker-compose. Typically, Compose V1 projects include a top-level
version element in the compose.yml file, with values ranging from 2.0 to
3.8, which refer to the specific [file
formats](https://docs.docker.com/compose/intro/history/#compose-file-format-versioning).

> Version two of the Docker Compose command-line binary was announced in
2020, is written in Go, and is invoked with docker compose. Compose V2
ignores the version top-level element in the compose.yml file.
 
Also in `README.MD` show `Docker >= 24.0.0 & Docker Compose >= v2.26.1`.
so i want to remove the version.
