use head_branch for extracting tag

[Sahilb315]

Previously, the workflow extracted the tag from ‎github.ref, but this does not contain the tag name when triggered via ‎workflow_run. The updated workflow now uses ‎github.event.workflow_run.head_branch to reliably access the tag version for npm publishing from the previous workflow.
