Persist environment auto stop in correctly

What does this MR do?

We currently persist most of the metadata of pipeline jobs in ci_builds.options (or ci_builds_metadata.config_options). As we're adding more feature in .gitlab-ci.yml, this column is getting bloated, therefore we introduced ci_builds_metadata.environment_auto_stop_in column to persist the value in the #20956 (closed) story.

However, it turned out that we're still persisting the value into ci_builds.options. So this MR is fixing the problem that we only persist the value into ci_builds_metadata.environment_auto_stop_in and not ci_builds.options.
