fix: read release version from candidate

[nicholls73]

Summary

• read the release version from the release PR head commit
• dispatch automatic approval with that exact version

Why

Release Please's PR output does not include a version field, so the automatic dispatch failed before creating Release v0.7.1.

Validation

• live lookup against release PR chore(main): release 0.7.1 #101 returned 0.7.1
• workflow YAML and embedded Bash syntax
• pnpm lint
• pnpm build
• pnpm test (128 passed, 1 skipped)

Summary by CodeRabbit

• Bug Fixes
  • Release approvals now use the version from the prepared release change, improving accuracy and preventing mismatches with manually supplied release details.
