license_stamper.py not resolving check_stamped.py errors

[eddieliao]

Running tools/license_stamper.py doesn't seem to be resolving the errors returned by check_stamped.py run by CI test.

This commit 355bc3f in my draft PR here fails the licensing check with the following error message:

Error: The licenses for the following 6 file(s) either... do not match the year of commit, have a different copyright format or have not been synced from the latest weight_streaming branch:
['src/include/migraphx/float8.hpp', 'test/fp8e4m3fn.cpp', 'test/fp8e4m3fnuz.cpp', 'test/fp8e5m2.cpp', 'test/fp8e5m2fnuz.cpp', 'test/verify/test_reduce_op_large.cpp']

However, running python3 tools/check_stamped.py weight_streaming locally returns that everything is up to date. If I use the pull request ref python3 tools/check_stamped.py pull/3222/merge returns a different set of failing files:

Error: The licenses for the following 15 file(s) either... do not match the year of commit, have a different copyright format or have not been synced from the latest pull/3222/merge branch:
['dev-requirements.txt', 'src/api/api.cpp', 'src/api/include/migraphx/migraphx.h', 'src/api/migraphx.py', 'src/include/migraphx/float8.hpp', 'src/targets/cpu/fuse_ops.cpp', 'test/api/test_cpu.cpp', 'test/fp8e4m3fn.cpp', 'test/fp8e4m3fnuz.cpp', 'test/fp8e5m2.cpp', 'test/fp8e5m2fnuz.cpp', 'test/verify/test_reduce_op_large.cpp', 'tools/api/api.cpp', 'tools/api/migraphx.h', 'tools/cppcheck/migraphx.py']
There is a license_stamper script (./tools/license_stamper.py), which you can run to automatically update and add any needed license stamps

Trying to use the license stamper with python3 tools/license_stamper.py doesn't seem to work for me; it doesn't update any of the files mentioned in either of the error messages.
