Make index in closeOtherTabs and closeTabsAfter optional (#7390)

## Summary of the Pull Request
The `index` action argument is now optional for `closeOtherTabs` and `closeTabsAfter`. When `index` is not defined, `index` is set to the focused tab's index.

Also, adds the non-index version of these actions to defaults.json.
