That warning can be ignored as long as the scaffold is generated and that the git patches
apply.
The Forge script issues that warning when it sees a version it didn't recognize. When
the script was written, 1.4.3 didn't exist yet. The changes in 1.4.3 are not expected
to break anything in the script, so you could use it.
