Description
Describe the enhancement
Self-hosted GitHub actions should have an attribute (weight) that allows to prioritize them, i.e. If there are multiple idle runners with matching labels, then the weight attribute would determine which runner to use first, e.g. prioritized in ascending order.
Additional information
For context, the reason this is needed is because the current implementation randomly picks an available runner. However, imagine that you are scaling up and down runners depending on how long they have been idle. Using random allocation mechanism, there is no way to determine (efficiently) how long the runner was not in use. As a result, we have a large portion of VMs runnings that are not in use most of the time.
Prioritization would allow more efficient resource packing.

Research direction
No source file or test is named; start by tracing the runner-selection path described in the issue, where matching idle self-hosted runners are chosen. Done means supporting a runner weight attribute and selecting matching idle runners in ascending weight order, with tests covering the prioritization behavior.
