fix: resolve multi-line string issues in all workflows

- Fixed integrate-develop.yml: Use here-doc for PR body
- Fixed release-staging.yml: Use here-doc for PR body
- Fixed update-version.yml: Use here-doc for PR bodies
- Fixed release-tag.yml: Use here-doc for release notes

All workflows now properly handle multi-line strings with GitHub Actions expressions
