Angular 14 (#1420)

* Updated to Angular 14

* Fixed all new tslint issues

* Fixed a routing bug for Angular 14

* Updated ngBootstrap and bootstrap. Fixed side nav item not highlighting on route change

* Refactored how default dark styles are done

* Migrated everything to a typed form

* Bump versions by dotnet-bump-version.

* Fixed a regression where click areas need an explicit z-index

* Cleanup some css

* Bumped docnet back to the alpha which has our downstream fixes

* Updated dependencies to later versions. Mainly just NetVips with some archive fixes.
