feat(ci): migrate workflows to Workload Identity Provider auth

[Teebor-Choka]

Summary

• Pins all hoprnet/hopr-workflows action/workflow refs to new OIDC-enabled SHAs
• Removes legacy gcp_service_account, google_credentials, and GH_RUNNER_TOKEN PAT from workflow inputs
• Adds id-token: write permission to every consumer job for OIDC token minting
• Adds github_app_private_key: ${{ secrets.GH_APP_HOPRNET_BOT_PRIVATE_KEY }} to all release-version invocations

Part of the org-wide WIF migration following the GitHub security incident. Reference: hoprnet/blokli#377

Warning

Review limit reached

@Teebor-Choka, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 26 minutes and 58 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

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 credits.

🚦 How do rate limits work?

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

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, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.
