Please add the dotnet6 runtime for the "AWS Lambda Deploy Function"-task

AWS Lambda now fully supports .NET 6, but this isn't mentioned in the AWS Lambda Deploy Function task yet. If you select the "Update code and configuration (or create a new function)" option you can only select dotnetcore3.1 and dotnetcore2.1 in the Runtime dropdown. Since .NET 6 is the new LTS for .NET Core it makes sense that the option for the .NET6 runtime is there as well.

Start by locating the AWS Lambda Deploy Function task and the Runtime dropdown used for “Update code and configuration (or create a new function). Inspect the task's existing runtime definitions and related tests, if present; done means .NET 6 is available as a selectable runtime alongside the current options.
