fix(hc): Move get participants test to region silo (#52483)

All `OrganizationRequestNotification` based notifications are being sent
from region silo endpoints so this moves the test case over to being a
region silo test.

For background, these classes inherit from
`OrganizationRequestNotification`:

- `AbstractInviteRequestNotification`
- `JoinRequestNotification`: Only sent from
`OrganizationJoinRequestEndpoint` (region_silo_endpoint)
- `InviteRequestNotification`: Only sent from
`OrganizationInviteRequestIndexEndpoint` (region_silo_endpoint)
- `IntegrationRequestNotification`: Only sent from
`OrganizationIntegrationRequestEndpoint` (region_silo_endpoint)
