fix: update pnpm to 11.0.0-rc.5

The existing version tests only check output format via regex, which is
why the PATH-shadowing bug (#230) slipped through — the bootstrap pnpm's
version string matched the regex just as well as the requested version.

- test_version_respects_request: runs the action with `version: 9.15.5`
  and `version: 10.33.0` (both differ from the bootstrap) and asserts
  that `pnpm --version` matches exactly. Regression test for #225/#230.

- test_package_manager_field: writes a `packageManager: pnpm@<v>` entry
  into package.json, runs the action with no `version:` input, and
  asserts exact match. Reproduces #227; currently expected to fail
  since `packageManager` extraction was intentionally not added.
