fix(ci): pass publish secrets explicitly to mbl-actionhub

[therajanmaurya]

Summary

• secrets: inherit fails to resolve required: true secrets when calling a reusable workflow in a different repository
• Pass each secret explicitly instead: MAVEN_CENTRAL_USERNAME, MAVEN_CENTRAL_PASSWORD, SIGNING_KEY_ID, GPG_KEY_CONTENTS, SIGNING_PASSWORD

Root cause

GitHub Actions error: "Secret MAVEN_CENTRAL_USERNAME is required, but not provided while calling" — secrets: inherit is unreliable for cross-repo reusable workflows with required secrets.

📝 Walkthrough

Walkthrough

The publish workflow job's secret propagation strategy is updated from implicit inheritance to explicit mapping. Only Maven Central and GPG-related secrets are forwarded to the MobileByteLabs/mbl-actionhub reusable workflow, replacing the blanket secrets: inherit approach.

Poem

🐰 A rabbit hops through actions grand,
Secrets now in careful hand,
No more inherited with haste,
Only what's truly needed, placed with taste!
Security springs from explicit care. 🔐✨
