[ci] Add short failing test summary for pytests (#24104)
It is sometimes hard to find all failing tests in buildkite output logs - even filtering for "FAILED" is cumbersome as the output can be overloaded. This PR adds a small utility to add a short summary log in a separate output section at the end of the buildkite job.

The only shared directory between the Buildkite host machine and the test docker container is `/tmp/artifacts:/artifact-mount`. Thus, we write the summary file to this directory, and delete it before actually uploading it as an artifact in the `post-commands` hook.

# This script is executed by Buildkite on the host machine.
# In contrast, our build jobs are run in Docker containers.
# This means that even though our build jobs write to
# `/artifact-mount`, the directory on the host machine is
# actually `/tmp/artifacts`.
# Here, we cat all text files in artifact-mount/test-summaries
# and upload them as a Buildkite annotation.
# These files contain a condensed summary of all failing pytest
# tests to make it easy for users to see which tests are failing.
# Because we upload them to Buildkite, we don't need to
# upload them as artifacts and delete them afterwards.
