Revert "Enable lints library_private_types_in_public_api, sort_child_properties_last and use_key_in_widget_constructors" (flutter#5691)

This reverts commit 4b7b679.

This includes a fix for a latent bug in the version-check repo tooling command that caused it to fail when reverting a package that previously had a NEXT section, so that tests will pass.
