chore(base-images): sync INDEX_URL from versions_config aipcc_wheel_index

[ide-developer]

Summary

• Add release.aipcc_wheel_index.{stream,use_test} to versions_config.yml / schema.
• Extend make sync-build-args-from-versions to rewrite base-images/build-args/*.conf INDEX_URL via index_url_resolver helpers.
• Seed to 3.5-EA2 / use_test: true (normalizes ROCm onto the shared test stream; content bump to 3.6-EA1 is a separate PR).

Fixes #4330

Companion

Direct INDEX_URL bump to 3.6-EA1-test: #4331 — prefer merging that first if base rebuilds are urgent.

Test plan

• uv run pytest tests/test_versions_config_schema.py tests/unit/scripts/test_update_build_args_from_versions.py
• After merge, mid-release index changes are edit versions_config.yml + make sync-build-args-from-versions only

Warning

Review limit reached

@jiridanek, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 52 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📋 Review Summary

This pull request introduces valuable automation for synchronizing AIPCC wheel index INDEX_URL configurations in base images from versions_config.yml. The implementation is robustly covered by JSON schema definitions, Python updater logic, documentation updates, and unit tests. No issues or required changes were identified in the diff.

🔍 General Feedback

• The separation of concerns between release metadata and the AIPCC wheel index stream (aipcc_wheel_index) is clean and well-documented.
• Comprehensive unit tests successfully cover the new schema validations, expected configuration structures, and strict error handling for missing or malformed configuration values.

I did not post any inline review comments.
