Bump assorted_layout_widgets to 4d10d7f9a64b4ddacf9ad7803d63dcfa84227287 (#470)

This bumps `assorted_layout_widgets` to the latest version. The current version is around 10 months old and excludes some changes made to remove obsolete lints that are preventing landing a change to the analysis server to produce warnings for that.

Specifically, we want the PR from @pq merged at marcglasberg/assorted_layout_widgets#37 that removes `prefer_equal_for_default_values` and mine merged at marcglasberg/assorted_layout_widgets#41 to fix the error we found at #469 to unblock my change at https://dart-review.googlesource.com/c/sdk/+/448063.
