chore: set schedule of lock closed issue

[Shinigami92]

Description

Set the schedule back to a value not so aggressive as we made for the bulk processing, see #4278
I set it to every 7-th day, cause 14-day would be to few
In the last 2 weeks we have already more then 70 issues closed, so the process would not catch up if we set it to low
