cli/command: remove deprecated DockerCli.Apply

The Apply method was added when CLI options for constructing the CLI were
rewritten into functional options in [cli@7f207f3]. There was no mention
in the pull request of this method specifically, and this may have been
related to work being done elsewhere on compose-on-kubernetes or the
compose-cli plugin that may have needed options to modify the CLI config
after it was already initialized.

The CLI itself no longer depends on this method since [cli@133279f], and
there are no known external users. It was deprecated in [cli@24bfedf],
which is included in the 28.5.0 release, so we can remove it for 29.0.

[cli@7f207f3]: 7f207f3
[cli@133279f]: 133279f
[cli@24bfedf]: 24bfedf
