test(deps): install pnpm with npm

[MikeMcC399]

This PR removes the dependency on the JavaScript GitHub Action pnpm/action-setup.

Background

pnpm/action-setup was last updated on Jul 26, 2023 to pnpm/[email protected]. This version supports only node16 version and causes deprecation warnings when run on GitHub:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: pnpm/action-setup@v2. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

• node20 support pnpm/action-setup#99 was opened to request an update of the pnpm action to support node20. There is no clear indication about if / when this issue might be resolved.

The example-basic-pnpm.yml workflow does not use any of the parameters of pnpm/action-setup except version, so it is easily substituted by npm install -g pnpm.

Changes

In the workflow example-basic-pnpm.yml and README > pnpm, the step

      - name: Install pnpm
        uses: pnpm/action-setup@v2
        with:
          version: 8

is replaced by

      - name: Install pnpm
        run: npm install -g pnpm@8

Verification

Run example-basic-pnpm.yml and check that GitHub does not output any deprecation messages.

@MikeMcC399 Thanks for the thorough explanation as always. Looks good.

Note:

pnpm/action-setup@v3 for node20 was released on Feb 8, 2024.

There is currently no plan to use this version in the examples, since pnpm can be installed directly with npm in GitHub Actions.

See the documentation for pnpm/action-setup for details of this action.
