git status --porcelain is not working in CI

[berland]

There is a github workflow to check that the tests do not pollute the files on disk. This is not working for the moment, as it is failing due to wrong syntax in a sed command:

Run # Run this before the 'Test CLI' entry below, which produces a few files that are accepted for now. Exclude the wheel.
  # Run this before the 'Test CLI' entry below, which produces a few files that are accepted for now. Exclude the wheel.
  git status --porcelain | sed '/ert.*.whl$\|\/block_storage$/d'
  test -z "$(git status --porcelain | sed '/ert.*.whl$\\|\\/block_storage$/d')"

This problem seems to occur between sed version 4.5 (RHEL8: no error) and version 4.7 (on debian 10.13). Ubuntu 22.04 has sed 4.8.
