## Description

This PR updates the CI/CD workflows to use `pnpm` instead of `npm` for
publishing packages to NPM registry. The changes include:

1. **Preview generation**: Added `--pnpm` flag to `pkg-pr-new publish`
commands to ensure pnpm is used for preview builds
2. **Package publishing**: Replaced `npm publish` with `pnpm publish
--no-git-checks` across all 7 package publishing jobs (fast-check, ava,
jest, packaged, poisoning, vitest, worker)
3. **pnpm setup**: Added explicit `pnpm/action-setup` step to all
publishing jobs to ensure pnpm is available before Node.js setup
4. **Line number updates**: Updated zizmor.yml ignore rules to reflect
the new line numbers after adding pnpm installation steps

These changes ensure consistency with the project's use of pnpm as the
package manager and prevent potential issues with npm's git checks
during CI publishing.
