https://gitlab.com/gitlab-org/gitlab/-/merge_requests/160048 introduced a migration to update a default value for `snippets` table. This process has two steps: 1. [Add the SafelyChangeColumnDefault concern to the model and change the default in a post-migration](https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html#add-the-safelychangecolumndefault-concern-to-the-model-and-change-the-default-in-a-post-migration) (Done in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/160048) 1. [Clean up the SafelyChangeColumnDefault concern in the next minor release](https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html#clean-up-the-safelychangecolumndefault-concern-in-the-next-minor-release) - should be done in scope of this issue. To finalize the migration, we should cleanup `SafelyChangeColumnDefault` from the code after %17.3.
