`{help}` tags that don't specify the `file` parameter no longer work on windows
Seems to have broke in 5.57 with https://github.com/civicrm/civicrm-core/commit/d80e8fa62cad6661a0882753a8babf5512f9bb12. Now it just throws an error.
An example is on the activity form if you click the help bubble for assignee.
I see - it's because on windows it doesn't match the regex because it has \
instead.
