[🐛 Bug]: [py][build] Test errors when run with Bazel on Windows (long paths)

[cgoldberg]

Description

Several Python tests fail when running with Bazel on Windows. They pass with Bazel on Linux, and also pass on Windows when run directly with pytest instead of Bazel. I get a cannot shorten the path enough error (see below).

This seems to be caused by how Bazel handles long paths on Windows: bazelbuild/bazel#22532

Reproducible Code

bazel test //py:common-chrome-bidi-test/selenium/webdriver/common/executing_async_javascript_tests.py
