ci: avoid failures when yarn unlinks bazelisk in windows jobs (#43373)
ci: avoid failures when yarn unlinks bazelisk in windows jobs (#43373)

Windows disallows removal of files which are currently being used.
i.e. have active handles. This currently can result in permission denied
failures on the Windows CI jobs where `yarn bazel` resolves to the local
bazelisk installation that can be unlinked by `yarn_install` repository
fetching as part of the Bazel invocation, resulting in errors like:

```
ERROR: An error occurred during the fetch of repository 'npm':
   yarn_install failed: $ node tools/yarn/check-yarn.js
...

 (warning " > tsickle@0.34.3" has incorrect peer dependency "typescript@~3.3.1".
error An unexpected error occurred: "EPERM: operation not permitted, unlink 'C:\\users\\circleci\\ng\\node_modules\\@bazel\\bazel-win32_x64\\bazel-0.27.0-windows-x86_64.exe'".

```

We workarund this in order to improve CI stability in case the node modules are
being invalidated by Bazel, or through Yarns integrity checking.
