Is this a regression?

I'm not certain whether this is a regression. I don't recall seeing the issue. No one had reported it to me previously. But that doesn't mean it didn't exist.

Description

When you create a new Angular project using ng new with an upper case or mixed case name, the Angular CLI correctly converts the name to lower case for the keys in the package.json file. It does not convert the name to lower case for the keys in the angular.json file. See the "Minimal Reproduction" for screen shots.

🔬 Minimal Reproduction

ng new Hello-World

Resulting package.json file correctly lower cases the project name:

Resulting angular.json file does not lower case the project name, resulting in an error (see below):

Notice the resulting error:

🔥 Exception or Error

Property Hello-World is not allowed
