There has been no release of the deprecated 'docker-compose' Python
package since v1.29.2, which was published in May 2021[1]. This release
is currently broken due to a breaking change in the 'docker' Python
package at version 7.0.0[1], and there is seemlingly no plan to release
a patch version of Compose v1 to address the problem.
The official path forward is to use Compose v2, which is now bundled
with the Docker client and available on all platforms where Docker is
supported.
This commit additionally removes the 'version' attribute from Compose
files, since it was obsoleted in the Compose Spec[3].
