chore: switch lint workflow to pnpm and update e2e install docs

- replace Bun setup in .github/workflows/lint.yml with Node + corepack-driven pnpm so linting aligns with the rest of the CI pipelines
- run lint commands through pnpm to ensure they use the workspace lockfile
- update packages/e2e/README.md installation section to point to pnpm add instead of bun install
