Verify GitHub workflow permissions compliance - all files already compliant

[Copilot]

Summary

After thorough analysis of all GitHub workflow files in the repository, I found that the OpenTelemetry Operator repository already has minimum token permissions properly implemented for all workflow files according to OpenSSF Scorecard recommendations.

Analysis Results

✅ All 25 workflow files passed verification with no errors or warnings

Current State:

• All workflows have root-level permissions: blocks
• Most use the recommended permissions: contents: read format
• Some workflows appropriately have job-level permissions for specific operations
• No workflow files are missing permissions blocks

Files Verified:

• changelog.yaml
• continuous-integration.yaml
• dependency-review.yml
• e2e-junit-report.yml
• e2e.yaml
• fossa.yml
• ossf-scorecard.yml
• publish-autoinstrumentation-*.yaml (6 files)
• publish-images.yaml
• publish-must-gather.yaml
• publish-operator-bundle.yaml
• publish-operator-hub.yaml
• publish-operator-opamp-bridge.yaml
• publish-target-allocator.yaml
• publish-test-e2e-images.yaml
• release.yaml
• reusable-operator-hub-release.yaml
• reusable-publish-test-e2e-images.yaml
• scorecard.yaml
• shellcheck.yaml

Verification Process

Created a comprehensive Python script that:

1. Parses all YAML workflow files using PyYAML
2. Verifies root-level permissions compliance
3. Analyzes job-level permissions for context
4. Provides detailed reporting on compliance status

The verification confirmed that the repository already meets the OpenSSF Scorecard Token-Permissions requirements and no changes are needed.

Fixes #15.
