Add docker file for running oidc-debugger

[CrowdHailer]

I don't use ASP.NET. I will probably set up a docker container to run this locally. would you accept a PR to add it to this project

I'm actually struggling to find the appropriate container to run a ASP.net application.

I have tried docker run mcr.microsoft.com/dotnet/core/aspnet:3.1
However, that gives me the following error.

It was not possible to find any installed .NET Core SDKs
  Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
      https://aka.ms/dotnet-download

Edit

I think this is probably the correct template https://github.com/dotnet/dotnet-docker/blob/master/samples/aspnetapp/Dockerfile

This is a great idea. I'll see if I can add a dockerfile.

Currently, this project targets ASP.NET Core 2.0, which is outdated. It would probably work with a 2.x runtime Docker image, but ultimately I should update it to ASP.NET Core 3.0+.

This would be awesome.
Probably in JS land I don't need to run it locally but it would be easier for tackling #24 if I could run it locally

Any update on this ?

@jsalatiel Unfortunately I don't have time to work on this project myself right now, but I am always open to PRs.
