fix: use locale-neutral Windows ACL for build data

On localized Windows installs, resolving the English Everyone principal can fail when build_data_writer.ps1 creates the output file ACL. This breaks build data generation on systems such as German Windows.

Use the language-neutral WorldSid identity instead, preserving the existing Everyone read permission without depending on localized account names.
