Fix E2E PnP Angular workflow cache corruption issue

[Copilot]

The E2E PnP Angular workflow fails with ERR_MODULE_NOT_FOUND when the yargs package in Yarn's cache becomes corrupted.

Changes

• Added yarn cache clean before yarn dlx to clear corrupted cache entries
• Added --no-cache flag to yarn dlx command to force fresh package downloads

- name: 'Running the integration test'
  run: |
    source scripts/e2e-setup-ci.sh
    
    # Clear Yarn cache to prevent corrupted package issues
    yarn cache clean
    
    yarn dlx --no-cache -p @angular/cli@next ng new berry-angular --interactive=false --package-manager yarn
    
    cd berry-angular
    yarn ng build --aot

This prevents the workflow from using potentially corrupted cached packages that cause module resolution failures.

Original prompt

Problem

The E2E PnP Angular workflow is failing with the following error:

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/tmp/xfs-4ba0ca9e/dlx-2242/.yarn/cache/yargs-npm-18.0.0-ec82bf7b61-bf290e4723.zip/node_modules/yargs/build/lib/utils/apply-extends.js'

This error occurs because the yargs package in Yarn's cache is corrupted or incomplete.

Solution

Update the .github/workflows/e2e-pnp-angular-workflow.yml file to clear Yarn's cache before running the yarn dlx command and use the --no-cache flag to ensure fresh package downloads.

Changes Required

In the file .github/workflows/e2e-pnp-angular-workflow.yml, update the "Running the integration test" step (lines 27-37) to:

- name: 'Running the integration test'
  run: |
    source scripts/e2e-setup-ci.sh
    
    # Clear Yarn cache to prevent corrupted package issues
    yarn cache clean
    
    # TODO: Angular should be fixed to detect the correct package manager to install with
    # but for now we need to specify it
    yarn dlx --no-cache -p @angular/cli@next ng new berry-angular --interactive=false --package-manager yarn
    
    cd berry-angular
    
    yarn ng build --aot

The key changes are:

1. Add yarn cache clean before the yarn dlx command
2. Add --no-cache flag to the yarn dlx command to force fresh downloads

This will resolve the ERR_MODULE_NOT_FOUND error by ensuring packages are downloaded fresh rather than using potentially corrupted cached versions.
