It looks like this is the change that renamed the files and introduced the issue: https://chromium.googlesource.com/external/github.com/tc39/test262.git/+/834789514d095d8055cdb12e2b4df40fedd5f5e7
FWIW, it looks like this can be worked around locally in Windows 10 by using Group Policy to turn on "Enable Win32 long paths" in Computer Configuration > Administrative Templates > System > Filesystem and running `git config --system core.longpaths true` from an administrative command prompt. I didn't find a solution for CI loops (build agents) though.
