Deduplicate DORA chart visibility flag names
What does this MR do?
Combines two flags - should_render_deployment_frequency_charts
and should_render_lead_time_charts
- that controls the visibility of the DORA 4 charts on the project-level Analytics > CI/CD page.
The new flag is named should_render_dora_charts
.
This MR makes no user-facing changes.
