Remove broken issuable time tracking report sorts
What does this MR do and why?
Related to #441254 (closed)
We have columns configured with sortable but gl-table-lite
doesn't support that.
As it wasn't working anyway, we'll just remove it for now.
How to set up and validate locally
- Log some time on issue/merge requests, view the time tracking report from the sidebar and make it sure it looks the same as before
