CSV Export Button should not be visible when the instance level dashboard is not configured
**Steps to reproduce**
1. Find `More` at the top level navigation and click on that
2. Click on Security Dashboard
3. Make sure it's unconfigured (if it's configured, click on edit dashboard and remove all associated projects).
**Expected**
The CSV Export button is not available.
**Actual**

**Implementation plan**
- [ ] Add a simple `if` statement to the `csv-export-button` in `ee/app/assets/javascripts/security_dashboard/components/first_class_instance_security_dashboard.vue`. If `shouldShowEmptyState` is true, we shouldn't display the button.
**Edit**
While [this MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36843) follows the implementation plan and hides the button for unconfigured dashboards - there is now a new bug which displays the button for a second till the projects information is fetched. Here is a gif which explains the bug better:
