fix(helm-publish): fix secrets reference in if condition

[samuelho-dev]

Summary

GitHub Actions doesn't allow direct secrets references in if: conditions for reusable workflows. This PR moves the secret access to an environment variable and checks it at runtime.

Changes

• Modified Import GPG key step to check for GPG key at runtime instead of in if: condition

Test plan

• Trigger helm-publish workflow in ai-dev-env after merging this fix

Summary by CodeRabbit

• Chores
  • Enhanced Helm chart publishing workflow with improved GPG key handling. The workflow now gracefully manages chart publication whether GPG keys are available or not, providing better error handling and control flow for more reliable publishing regardless of signing configuration.

Walkthrough

Modified the Helm publish workflow's GPG key import step to use conditional logic with an environment variable instead of relying on a step-level condition. The GPG key is now imported only if the environment variable is non-empty, otherwise a warning is logged and the step proceeds.

Changes

Cohort / File(s)	Summary
Helm Publish Workflow .github/workflows/helm-publish.yml	Refactored GPG key import step condition: moved from step-level check of secrets.gpg-private-key to conditional logic within the step using GPG_KEY environment variable. Now gracefully skips import with a warning when no key is provided.

Poem

🐰 A hop through CI, so sleek and bright,
GPG keys now conditional, just right!
No more harsh failures when secrets are bare,
A warning whispered through the publish air. 🔑✨
