Remove migration script accidentally committed in #79173

Summary

• Remove migrate_slack_to_inline.py that was accidentally included in prowgen: remove no-op multi_arch from .config.prowgen #79173

🤖 Generated with Claude Code

Summary

This PR removes the migrate_slack_to_inline.py script that was accidentally included in PR #79173. This was a one-time migration utility designed to convert OpenShift CI's slack notification configuration from being centrally defined in .config.prowgen files to being specified per-test in individual ci-operator/config/**.yaml files.

What changed

The removed script contained helper functions for the migration process, including logic to:

• Parse ci-operator configuration file naming conventions (org/repo/branch/variant)
• Match slack reporter entries to test definitions based on job types (pull/branch/periodic)
• Generate per-test reporter_config blocks for individual tests
• Process all affected CI configuration YAML files and update them with the migrated settings
• Remove or retain the original .config.prowgen files after migration

The script was a temporary utility used to support the actual configuration migration work (PR #78976) and should not have been committed to the release repository.

Impact

No functional impact — this is purely housekeeping to remove accidental tooling that was left in the main repository. The actual slack reporter migration to per-test configuration has already been completed and is captured in the modified CI operator config files across the repository.

Walkthrough

The migrate_slack_to_inline.py script was removed. This script previously automated migration of slack reporter configuration from org/repo .config.prowgen files into per-test reporter_config fields within ci-operator/config YAML files, including job type inference and partial match warnings.

Changes

Cohort / File(s)	Summary
Script Removal migrate_slack_to_inline.py	Removed entire migration script containing nine functions that handled parsing config filenames, matching slack reporter entries to tests, building reporter configurations, and processing YAML files with optional dry-run support (380 lines).
