Update the version requirement on urdfdom so it works with version 4.0

[azeey]

Environment

• OS Version: Ubuntu 22.04
• Source or binary build? sdf12

Description

ros/urdfdom#186 is updating urdfdom to 4.0 and making the find_package logic more strict about version numbers. It's not clear if it will break sdformat since

sdformat/CMakeLists.txt

Line 41 in eee0af8

ign_find_package(IgnURDFDOM VERSION 1.0 QUIET)

requires anything newer than 1.0. But the change in ros/urdfdom#186 might make it so it only finds versions with the same major version.

Things to try

• Just remove the VERSION 1.0 and see if it works since liburdfdom versions in all platforms we support is newer than 1.0
• Add logic that also looks for 4.0
