Add ARO-HCP dev shard2 and shard3 Boskos slot pools

[raelga]

Adds Boskos slot pools for two new ARO-HCP DEV E2E customer subscriptions (shard2, shard3), synced from test/e2e-config/e2e-slots.yaml in Azure/ARO-HCP via aro-hcp-tests slot-manager sync-boskos-config.

• generate-boskos.py: registers aro-hcp-dev-shard2-slot and aro-hcp-dev-shard3-slot (1 slot each).
• _boskos.yaml: regenerated (make boskos-config) — adds aro-hcp-dev-shard2-slot-00 and aro-hcp-dev-shard3-slot-00.

Validated with slot-manager validate-boskos-config against the slot catalog. Companion ARO-HCP PR: Azure/ARO-HCP#5576. Tracking: ARO-27549.

Summary by CodeRabbit

This pull request expands the Boskos resource pool configuration to support two new ARO-HCP DEV E2E test shards (shard2 and shard3). ARO-HCP is an Azure Red Hat OpenShift Hosted Control Plane offering, and these new shards represent additional isolated test environments for customer subscription E2E testing.

What changed:

• generate-boskos.py: Updated the Boskos configuration to register two new slot resource types (aro-hcp-dev-shard2-slot and aro-hcp-dev-shard3-slot), each provisioning one slot resource
• _boskos.yaml: Regenerated configuration file now includes the corresponding Boskos free resource entries for these new slots (aro-hcp-dev-shard2-slot-00 and aro-hcp-dev-shard3-slot-00)

Practical impact: The OpenShift CI infrastructure can now allocate test resources to the two new ARO-HCP DEV shards, enabling E2E testing for these additional customer subscription environments. The configuration was generated using the ARO-HCP slot-manager tool and validated against the slot catalog before submission.

Related: This syncs configuration from Azure/ARO-HCP repository (PR #5576) and tracks ARO-27549.

Walkthrough

This PR adds two new ARO-HCP development resource slot types (shard2 and shard3) to the Boskos resource manager configuration. The generator script is updated to declare these new slot types and populate one resource for each, with the output reflected in the generated YAML configuration file.

Changes

ARO-HCP Shard2 and Shard3 Resource Slots

Layer / File(s)	Summary
Generator script and YAML configuration for shard2/shard3 slots core-services/prow/02_config/generate-boskos.py, core-services/prow/02_config/_boskos.yaml	Generator script CONFIG dictionary adds aro-hcp-dev-shard2-slot and aro-hcp-dev-shard3-slot quota-slice entries, resource population logic creates one resource for each new shard slot type, and the generated YAML output defines the two new free resources matching the script configuration.

• openshift/release#77407: Both PRs modify the same Boskos generation pipeline (core-services/prow/02_config/_boskos.yaml and core-services/prow/02_config/generate-boskos.py) by adding new ARO-HCP dev resource declarations produced by generate-boskos.py (though for different resource types: shard2/shard3 slots vs CD/image-push quota slices).
