feat: update package.json in v5 migration recipe

[Vinayak1337]

Fixes #113

Summary

• add package.json dependency update logic directly to the v5 migration recipe
• update existing package entries that match current direct dependencies from express@5.2.1
• update related Express type packages
• cover dependencies, devDependencies, peerDependencies, and optionalDependencies
• preserve the original package.json line endings when rewriting files

Tests

• npm run test --workspace @expressjs/v5-migration-recipe
• npm test
• npm run lint
• npx codemod workflow validate --workflow codemods/v5-migration-recipe/workflow.yaml
• verified the update map covers all current express@5.2.1 direct dependencies without missing or extra entries
• npx codemod jssg run --language json --target codemods/v5-migration-recipe/src/package-json.ts --allow-dirty --no-interactive, then diffed against the expected output
• npx codemod workflow run --workflow codemods/v5-migration-recipe/workflow.yaml --target --allow-dirty --no-interactive, then diffed package.json against the expected output
• verified CRLF package.json input keeps CRLF output to cover Windows checkout behavior
• git diff --check
