Wrong german title for pipeline schedules

The german title for the Schedules page has a typo. The title of the page is Zietpläne but it should be Zeitpläne.

In the content of the page the string is correct.

The problem is here:

https://gitlab.com/gitlab-org/gitlab-ce/blob/master/locale/de/gitlab.po

msgid "Pipeline Schedules"
msgstr "Zietpläne der Pipeline"

this should be

msgid "Pipeline Schedules"
msgstr "Zeitpläne der Pipeline"
