Remove extra not null assertions (#202201)
* Remove extra not null assertions

With https://github.com/microsoft/TypeScript/pull/56908, TS should better preserve type refinements. To help test this out, I made a quick pass through our code to remove type assertions that are no longer needed

Most of these are not impacted by https://github.com/microsoft/TypeScript/pull/56908 but removing them helps TS test changes like this

Not adding an eslint rule for now as it requires whole program intellisense, which is too slow for commit hooks

* Fix merge
