Summary

The existing problem that is solves it that on some computers, with some installations on Git Bash https://gitforwindows.org/ . See also the corresponding issue #5349 .

It's not a big change, therefore I don't update CHANGELOG.md .

Test plan

With https://gitforwindows.org/ simply run for instance:

yarn --version
