Remove confusing and duplicative item in Video Calls section

Why is this change being made?

In Communications > Video Calls > item 3 > subitem 4 The following sentence is grammatically confusing and redundant with subitem 3.

"The expectation is that you are groomed when you meet a family member or close friend is fine for GitLab internal meetings (including if you just got back from a run)."

This change (after consultation with PeopleOps in Slack) removes this problematic sentence.
