Get a list of Holdouts within a Project.

Holdouts are experiments that reserve a portion of your traffic to measure the impact of your feature flags and experiments. They help establish a control group by excluding a percentage of users from seeing any experiments, allowing you to measure the overall impact of your experimentation program.

You can use query parameters to filter and sort the response. Holdouts can be in different states (draft, running, concluded) and can be scoped globally or locally within your project.
