Sorry tiny change,
Can you add the group_id in both variables file with optional(null). And enable the line in the main.tf. The next branch is on provider 6.21

Description
This PR adds support for configuring EC2 placement groups for GitHub Actions runners in the multi-runner module. It plumbs a new placement option from the runner configuration through to the underlying EC2 runner module.
Details
Updated modules/multi-runner/runners.tf to pass placement = each.value.runner_config.placement into the runners module.
This allows specifying AWS placement groups for EC2 runners, enabling tighter control over instance placement.
The change is backwards compatible: if placement is unset in runner_config, behavior remains unchanged.
Motivation / Future work
Placement groups are a prerequisite for supporting macOS runners, which require a host_id.
A follow-up PR will add explicit macOS support leveraging this new placement wiring.
