The recent release of build 2.5.0 seems to have accidentally included a breaking change. The latest version of build_test works with build 2.5.0, but the latest version of build_test is 3.x, and go_router_builder is currently using 2.x.

I'm going to temporarily restrict go_router_builder to depend on build <2.5, but since build is a non-dev dependency this is likely to cause issues for go_router_builder clients, and regardless it's going to become a problem for us at some point as well as other things start hitting transitive dependency version conflicts.

go_router_builder should be migrated to build_test 3.x (and the build restriction removed) ASAP, before the older dependency causes a new set of tree-blocking issues.
