ICU-to-flutter roller has been failing for multiple weeks #149684
Description
Steps to reproduce
A google-internal mechanism for rolling ICU updates to Flutter has been failing.
I think the issue is due to licensing text changes. (Why they have to keep it changing is beyond me but here we are.)
Expected results
The roll succeeds.
Actual results
The license check fails.
failure: failed to handle ../../../flutter/third_party/icu/LICENSE
could not parse ICU license file
