fix: resolve action compatibility and release tag issues

[brendanjryan]

Summary

This PR fixes two issues that were breaking the tempo-lints GitHub Action:

1. pnpm version conflict in action.yml

Problem: The action hardcoded version: 9 for pnpm, which caused errors in projects using packageManager: "pnpm@10.x" because pnpm/action-setup@v4 throws when multiple pnpm versions are specified.

Fix: Replace pnpm/action-setup with corepack enable, which respects the action's own packageManager field.

2. Missing v0 tag due to release workflow mismatch

Problem:

• The README documents using tempoxyz/lints@v0
• release-tags.yml expects tags matching ^v([0-9]+)\.([0-9]+)\.([0-9]+)$ to create major version tags
• But changeset tag creates tags like @tempoxyz/lints@0.1.1
• The regex never matched, so v0 was never created

Fix:

• Updated release.yml to create a vX.Y.Z tag from the changeset tag before creating the GitHub release
• This allows release-tags.yml to properly create/update the major version tag (v0)

Manual tag creation

I also pushed v0.1.1 and v0 tags manually to fix the existing release:

• v0.1.1 points to the same commit as @tempoxyz/lints@0.1.1
• v0 points to v0.1.1

Test plan

• Verify tempoxyz/lints@v0 now resolves correctly in GitHub Actions
• Test the action in a project using pnpm 10+
• Verify future releases create proper vX.Y.Z tags
