Fix pipeline failures(feature_category/liquibase/rubocop)

What does this MR do and why?

1. Undefined method feature_category_not_owned! Upstream removed feature_category_not_owned! in https://gitlab.com/gitlab-org/gitlab/-/commit/e63d5187bf09a394cf273bec508a98ba93d0bd7f, So I update feature_category_not_owned! to feature_category :not_owned

2. add Database/liquibase.gitlab-ci.yml

3. Fix rubocop error for line length over 120
