Move Tye to .NET 6 (#1215)

* Switch to .NET 6 runtimes.

* 1st pass at moving core project target frameworks.

* 2nd pass of nullable updates.

* Use .NET 6 SDK base image for Docker proxies.

* Move test projects to .NET 6.

* Fix formatting.

* Try running tests on MacOS 11 (Big Sur).

* Try disabling HTTPS on watch tests.

* Revert HTTPS changes and just disable E2E tests for now.

* Update docs references to .NET Core.

 This is also where Tye requires a container registry to properly set the image name. If running `tye deploy` (no interactive), tye requires a registry to be defined in `tye.yaml`. If running interactively (`tye deploy -i`), tye will prompt the user for one if not specified in `tye.yaml`.
