Subject: [PATCH] [webview_flutter] Use a local web server for legacy web
 integration tests (#5956)

Use a local web server for the legacy test, just as for the non-legacy version.

Also updates the repo tooling to ensure that this test file is found, so it's run regardless of whether tests are run by directory or by individual path.
