Drop upper limit for Typescript peerDependecy

🐞 bug report

Affected Package

@angular/cli

Is this a regression?

Somewhat

Description

Typescript version is locked within range.

🔬 Minimal Reproduction

Not needed

🔥 Exception or Error

Angular asks for Typescript to be peerDependency within a certain range. I would expect it to not be that case as when upgrading from 7.x I was forced to downgrade Typescript from 3.5.x.

I suppose there need to be some minimal version required, but I don’t see any reason why prevent developers from using newer version if they op into it. I would understand a note about “incorrect” version at most.

@Akxe, you can opt to use unsupported TypeScript versions by using the disableTypescriptVersionCheck compiler option.

See: https://angular.io/guide/angular-compiler-options#disabletypescriptversioncheck

Note: that certain functionality might not work properly since the TypeScript version you will be using will be an unsupported version.
