ERR_PNPM_BAD_PM_VERSION error message clarity

[MarcoStrykerlabs]

An error in our pnpm/action-setup config by declaring the version property as "pnpm@###" lead to following error message:

- version pnpm@9.15.5+sha512.845196026aab1cc3f098a0474b64dfbab2afe7a1b4e91dd86895d8e4aa32a7a6d03049e2d0ad770bbe4de023a7122fb68c1a1d6e0d033c7076085f9d5d4800d4 in the GitHub Action config with the key "version"
- version pnpm@9.15.5+sha512.845196026aab1cc3f098a0474b64dfbab2afe7a1b4e91dd86895d8e4aa32a7a6d03049e2d0ad770bbe4de023a7122fb68c1a1d6e0d033c7076085f9d5d4800d4 in the package.json with the key "packageManager"
  Remove one of these versions to avoid version mismatch errors like ERR_PNPM_BAD_PM_VERSION

While it is a configuration error, the error message looks misleading as the printed versions are the same and could be more clear by showing the exact comparison done in
/src/install-pnpm/run.ts:

throw new Error(`Multiple versions of pnpm specified:
  - version ${version} in the GitHub Action config with the key "version"
  - version ${packageManager.replace('pnpm@', '')} in the package.json with the key "packageManager"
Remove one of these versions to avoid version mismatch errors like ERR_PNPM_BAD_PM_VERSION`)
