fix: use double quotes for environment variable assignments in workflows

- Updated environment variable assignments in multiple workflow files to use double quotes for consistency and to prevent potential issues with variable expansion.
- Refactored echo commands to group multiple lines into a single block for improved readability in the following workflows:
  - release-goreleaser.yml
  - renovate_prune.yml
  - security-pr.yml
  - security-weekly-rebuild.yml
  - supply-chain-pr.yml
  - supply-chain-verify.yml
  - update-geolite2.yml
  - waf-integration.yml
  - weekly-nightly-promotion.yml
