Description of the problem, including code/CLI snippet

It seems that existing config validation is not implemented (at least I haven't found it in the source code), but the documentation doesn't say it explicitly.

While this curl call works:

$ curl --header "Private-Token: ${MY_CI_TOKEN}" https://${MY_GITLAB_HOST}/api/v4/projects/${MY_PROJECT_ID}/ci/lint?content_ref=${MYREF}

This code doesn't:

from gitlab import Gitlab
g = Gitlab(my_gitlab_host, private_token=my_ci_token)
p = g.projects.get(my_project_id)
p.ci_lint.validate({"content_ref": myref})

Expected Behavior

If I pass only content_ref instead of content, the same GET would be called as in the curl above according to the GitLab documentation.

Actual Behavior

It executes new config validation as specified here, sends a POST call, then throws AttributeError: Missing attributes: content
