Update usage ping data to track projects with "Can override approvals in merge request" enabled/disabled

Problem to solve

Related to #220541 (closed)

We need to answer the question: How many projects have the Can override approvals in merge request option enabled/disabled?

Proposal

From #220541 (comment 358825262):

This can be done by querying the projects table and filtering by disable_overriding_approvers_per_merge_request column whether it's true or false.
