Issue:
Ability to hide `Number of items closed` Metric in the overview table
### Is your feature request related to a problem?

`Number of items closed` as shown in the screenshot does not have any meaningful value when running the action against Discussions. Discussions are normally marked as answered rather than closed.

### Describe the solution you'd like

I would like to have the ability to configure `HIDE_ITEMS_CLOSED_COUNT` env variable such that it is not reported in the markdown output.

### Describe alternatives you've considered

Just dealing with it 🤷
