Ensure the timeout of the `internal_release_release_build_package:*` jobs is of 2h

Context

Some internal release packages require waiting for the asset compilation to be completed on the dev instance. This is a lengthy job that usually takes ~80 minutes. To accommodate for that, the timeout was increased on this job gitlab-org/release-tools!3908 (diffs). However, when testing the job generated used a timeout of 50 minutes https://ops.gitlab.net/gitlab-org/release/tools/-/jobs/17444168

This could cause the jobs to timeout if an internal package requires waiting for the assets or if the dev instance has a slow performance.

Ensure the timeout the build_package jobs to be of 2h

Recently, the jobs were switched to be part of a downstream pipeline #20865 (closed). This may have caused the timeout to be overridden. This issue is to guarantee the build_package jobs respect the timeout of 2 hrs.
